The warpspeed is awesome! I runs through like its namesake!! It is tough and does not fade in the intese Florida sun. I use the 5/16" on a 8:1 setup. I was using 3/8" before. I like the 5/16" better personally. The ultra-lite frays quickly if you use the ratchets alot. I use the ultra for the spin.
2 cents....
