the main concern here is youth bowlers who by no means (most the time) are doing wat is natral, they are trying to throw big hooks, just like there favorite PBA star, or simply because it looks cool. There are some older crankers who can control the "power shot" BUT in kids under the are of 16 (YABA bowlers) most of them all want to throw a big hook and very few of them can control it.
I will join Easton in being a YABA bowler that has no want or means to rip the cover off the ball, from what i've seen the cranker can score about the same as the stroker but he will have a tendency to miss more, but get forgiving breaks, than the stroker (once again from YABA bowlers).
My 2 cents
