We have been using VP Pro all this year and absolutley love them, we mainly use axeman, ultra flexx in the colder weather and medium when its warm and low flexx on abrasive tracks and turbo track every so often. The inserts are strong and reusable, similar to AKA inserts, they are light weight(lot lighter than other PRO line of tyres) wear is great and best of all the price is right!!! best bet is pick some up, try them out and judge for yourself.

Cheers
Scott
