Well I tried my Action Packed today and do not find that I can't put as many revs or as much speed. I know if I used it all the time I'd get tired easier, but I don't plan on using a Scorchin' Inferno game after game. The lanes would eventually get too dry for it.k Plus, it's drilled for heavy. It's the 1E layout. The pitches are fine and everything. The thumb hole is just a tiny bit big, but I have some black tape to take care of that!
