I need to order some new main and jib sheets for the Isotope, I know there arent a whole lot of people on here that sail them but figured I'd ask anyway.

What size/length do I need for each? The main has a 4:1 system on it right now. Where is the best place to order the stuff from? I'd like to do two different colors for the jib sheets is possible, this is on a non-roller furling jib as well if that makes any difference.

Any recommendations on brand/type of sheet? This is all new to me

One more week and I'll have my boat ready to hit the water!
