The only caveat I'll give on the Code X is the need for surface upkeep. We had a bowler on our high school team punch a Code X, and that thing sucked up oil like a vacuum, and the kid using it wasn't a high rev guy, and he wasn't bowling on floods. Still, after about 30-40 games, that ball had to be put in the revivor forever and a day to bleed the oil out and get it hooking again!
