So I ripped my track in two the other day and I picked up a power claw. My question is should I just cut the outter nubs off and run the regular 3 pitch Wahl Bro drivers or spend the extra cash and get the Avid drivers made for the power claw? The one advantage I can see with the Wahl is if I decide to go with a Challenger Extreme I won't have to change drivers agian. But I would like some input on guys who have this track under the Pro and what drivers they are running.
