I got my full throttle yesterday and I absolutely love it. my book average is 163, but in the last month or so ive been averaging like 145. last nite i averaged about 180 with that ball. I bowl on a house shot, medium heavy. After league i bowled another 4 games and I had no problems with the lane getting too dry. Great ball. i've seen a few other people using the throttle/r and they're shooting great with it too. My driller also recommended the EGO for a medium oil ball. Hope all this helps. if not, SORRY
