[quote=Dogboy][quote=Andinista]Regarding price and quality of blocks, I don't have much experience with different brands and models, but I guess that friction is a relevant consideration for a mainsheet system.[/quote]
You can say that again. The amount of rolling resistance (friction) is what separates good blocks from cheap junk. A $10 pulley from a tractor supply house may roll freely in the store, but I guarantee that when you stack enough of them together to build a 7:1 system and then put a load on them, they're not going to work nearly as nicely as the blocks from a high quality, marine grade equipment manufacturer. Do you really want to be dealing with poorly functioning blocks that seize up or explode every other outing? The Harken (or Ronstan, or Lewmar, or other quality manufacturer) are designed for the task and last just short of forever with virtually zero maintenance. Well worth the money IMO.
