the shaved and heat is for track cars, less depth on the tread, makes them more like slicks.
I had V700s. Good traction. picked up everything.
I have PS2s, more $$ but IMHO a much better tire. Not picking up things and so far, appears to be close in traction.
Sidebar, the V700 looks odd due to the squared off sidewall in relation to tread, and has no rim protector (rim sticks out).
