Mucmore Absolutes are definatly the fastest tires. Extremely good grip, decent-ish were but the downside to them are the sweep rims. They are too brittle and brake too easily.
Sorex's are good but have no wear the grip that muchmores have.
I found a .2- .3 a lap differnece in the tires.
A friend of mine likes Jaco blues, but i havent a a run with them yet to compare them to the other two
