For the 01?
I think those sticks are a little on the small side for a 64. I think you would be much happer with the 62 at those levels.
You can grow into the 64, so it depends on what your eventual goals are for the truck. I'm running a set of 150s with my 62/68/14, and I think they are right at the limit. I'm happy with the performance, but it is a bit much going over a lot of the passes around here... I'll have twins some day.
