I'm trying to make some progress over the winter on a whole bunch of boat
stuff, one of the major items being getting a new tramp made for the Unicorn.
I have a history with a local tent+awning shop, and they've always done good
work for me, but they're far from cat specialists. Since we have the original to
work from, though, and it's not complicated, that just leaves the choice of
material.
Sailrite's "black tramp mesh" (old catalog #5624, new #562411) aka Tencate
Permatron 24109/24119 is the immediate obvious choice. Does anyone have
another preference or relevant experience that might point me elsewhere?

Really? 72 views and still crickets?
Does this mean that everyone agrees that this is the right answer? -

Cool, thanks. I've asked them for more detail - it may be the same material Sailrite carries.
If so, interesting to see that it really is the bouncy-bouncy trampoline stuff. -

Well like the "Ferrari" material for one. I don't think I spelled that right. Only thing is, for all the world of people ranting over the stuff, I've never actually experienced it in real life, so YMMV. In fact, I don't even know where to buy it. Vinyl would be more comfortable, but for me it's way too hot. I'm content with what I got, though.
This tramp is made with ProTramp material, heavy trucker vinyl for the perimeter along with some 3" polypropylene webbing for reinforcement, tenara thread and nickel plated grommets. Next one will be the same except I won't use fiberglass rods for the bolt rope; it'll be sail slugs from sailrite, sewn to the outer reinforcing with webbing, kind of like a clew ring and stainless grommets only on both sides, since I just bought a package of like 500 Hiker grommets...you can only buy them in bulk, so I need to grommet stuff I guess... But, with what I've learned, I'll definitely add a through-pocket for righting line, or at least one on the underside and build the halyard pockets off the tramp completely then sew them on. I'll still stay with PTFE thread despite the hassle. And, one-piece if possible as it is so much nicer for stuff not going through (water in and lines out).

Yeah, you got the spelling right - these guys:
https://www.sergeferrari.com/us-en/productsprotect-range/protect-meshes-392-s2
(and similar meshes they make like the 330/332, though not the ones made from coated steel cable...)
Looks a little overkill (and by extension, as you suggest, overprice) for a tramp for a small, light cat. I mean, how much do I care about the flame retardant ratings? And I'd just as soon stick with a simple weave rather than coated stuff.
"ProTramp"? Where can I see that?
To your other points: I get that you're tooled up for this stuff, and I normally like doing the same, but don't feel the urge in this case. I'll be improving upon the original pockets, but hadn't though about the righting line or halyard and will do so, though those seem like straightforward enough modifications/additions after it's been made i.e. don't need to happen with the initial fab. As for the bolt rope, I don't know why you'd have gone with the fiberglass rod - something rigid seems highly counterintuitive. And I'll check the track dimensions to see if the slugs can work, otherwise a conventional rope should be fine.
Incidentally, this is a two-piece tramp because there's a centerline spar between the fore and aft crosstubes. Not my favourite thing, but at least it's level with them rather than elevated above the rest of the tramp e.g. the Sea Spray 15, which is awful. The way they did it was bolt ropes threaded into the crossbeams and hull tracks, then the two halves laced together across that center tube. Contrary to your suggestion, I'm considering adding lacing gaps/grommets ahead of the aft crosstube to give me tensioning adjustment, though - again - that's something that can be added later if needed, and given that it's a una rig there's really not much chance of any lines washing through it. (I mean, that was the thing I hated about the H18 - the sheets constantly washing over the side, which was a real bitch esp. when soloing on the wire.)
But as far as material goes, unless this ProTramp stuff looks really great, the TenCate from Sailrite will probably be it.

the pro tramp stuff was my by description of the trampoline material by trampolineproshop (not sure if they're any "better", but their service and price is outstanding). https://www.trampolineproshop.com/trampoline-fabric.php
It's just standard trampoline mesh, made for...trampolines... It works. Your setup is way different than mine, which is essentially identical to a H18, only bigger. I used the rods out of necessity because the rope I was using was too fat as I decided to double up the vinyl on the perimeter. It just worked, definitely not better nor worse. Certainly stays put.
Just get the hammer-type spur grommet tool/dies and then just buy the grommets you need. That way you can by the widely available Stimpson spur grommets. Grommets and dies tend to be brand specific/compatible. Certainly so for the presses. I ended up picking up a hole punch set from hardware store for like making gaskets or something. Cheap and works well enough. The press punches the holes and sets the grommets in one step-nice...
Share pics; I love doing these projects, though I'm way behind...

Unless I wind up getting outrageous quotes for this tramp, I'm not going to roll my own - I don't have the sewing machine, nor the place to put it (at present). Of course, if the quotes begin to approach the cost of a capable machine, I'll reconsider.
I'm wondering about your use of slugs rather than a bolt rope, though. I don't think I'd have a problem wtih them in both the fore and aft crosstube slots, but not the hull tracks if they're going to leave any kind of gap that a finger or a toe can go awry in. If you use them there, how far apart do you space them? -

Slugs are just an idea - not tried yet. I've seen them somewhere else on a higher end cat, but can't recall where. The point of the matter is to have something that'll stay in that Keder rail, unlike the bolt ropes that tend to come out at the ends eventually. But, you have hit on a problem; the gaps around the perimeter. I'd have to sew on a vinyl flap to keep stuff from washing through, including toes. Not ideal. You know, Hobie and others have played this game quite a while, perhaps that simplicity says something (compromises everywhere to get to the best, most economical solution).
As for spacing, it appears that every 4-6 inches is the right placement for grommets, so I'd presume the same for slugs or any other tensioned reinforcement in mesh. Now that I think about it - that's a lot of slugs...

On second consideration, Hobie used the sail slugs already on the 21 SC, apparently?

I'm casting about for quotes for this tramp: The local tent+awning guys I mentioned previously; another local shop that builds actual bouncy-bouncy trampolines and has a passing familiarity with cats; Slo Sails.
Can anyone comment candidly on whether Slo gets their name from the speed of response when you're trying to get a quote out of them? -

Slugs are ok.. but, make sure the track will accept the slugs (there are different size tracks). Labor wise, a bolt rope is much easier and cheaper. It takes a bit of time to sew the webbing for each slug. I will use bolt rope on the front and starboard side with slugs on the port side. On the Prindle, I can use the standard sail slug, but on the Tornado, I had a material strip with a small bolt rope and it was laced to that. I got rid of the strip and made short dyneema loops that I use for lacing the tramp. Slugs will typically be spaced 6-8" apart. The gap makes a good hand hold especially in choppy conditions.
