as for the X-Driv tires, i like em. ive got a full set on my warrior and rears on the 300ex and they are great. damn good traction. they are 6-ply as well.
i think that youll like the klaws. Ive had mine for about 3 months now and they are great. I got both of mine shipped through dennis kirk for just under 100 for the pair (price match) and have been very pleased with them.
