I think i'm going to have to wait another month or so before ordering new r-compounds and I wanted to try some of this stuff as well. Anyone use it before? Whats a good place to shop for it? Lowest i have seen is about $38 for it

 

I have some vht...never thought about using it on the road course though. In for response.

 

I have used it and didn't care for it, made the tires feel greasy next time I raced. I bought it from Summit or Jegs, can't remember. I have never had a set of V710s get hard enough to need them before the rubber ran out.
