V-100 is too stiff for a mainsheet. I think you are referring to Dyneema Racing 2, Jake?
The "ice" is actually called Robline "Racing Sheet."
I like the racing sheet with spectra spliced to it.

Oh yeah, I'm in St. Thomas right now, on the beach, with a H16, a N5.8, and a Nacra 20, along with 6 of my good sailing friends. Man I love college...........
