I know how to crank the ball, I have been doing it for 25 years. Right now I have a problem that needs to be fixed in my mechanics, and I want to diversify my release options. How can you make a blanket statement about what line to play having never bowled on those lanes, with my equipment on that day? I know how to line up, and find a playable shot, but I want more options. Cranking the ball doesn't work ALL the time.
I too learned how to crank the ball many years ago, when all we had to work with was plastic, rubber, and a little top weight. When I came back to the game a couple of years ago, I got myself a new ball, and discovered that the equipment and lane conditions are not the same as in the old days. My shot was similar to your's... quick feet, low backswing, hit up hard... although my timing was later than your's, and my ball speed was less, with more hook. So, I understand what you're saying, I think. I found that, given a lane condition with decent oil, I could score OK. I averaged 213 last year on an easy condition. But even then, I just didn't think my carry was as good as some of the others, who were rolling an "easier"... ie "fluffier" shot. No fair, I thought! Then, when I would bowl on another day, other than regular league night, on a much drier condition, I completely stunk. Outside? No way. Normal 2nd or 3rd arrow? No way... hook up too hard, and too early. Ramp up the speed? Nope, ramping up the speed just caused me to ramp up the revs, as well. Move way in? Worse yet. Like you, major over/under reaction, and IF I did hit the pocket... 10 pin... every time.
So, I did some reading. Turns out that the old hit-up release doesn't work so well with the new cores and coverstock on the conditions that are out there. When you crank on it, you kinda take the new technology out of the equation. The coverstock will still grab the lane, but the new-fangled cores aren't allowed to work like they can/should.
So, I changed. No more hit-up cranker for me. Now, my shot is a long, smooth swing, with the load/unload wrist snap. It's been a bear to change... so different from before. But, it's coming along pretty good. Carry is better, and there are many more options as far as lines to the pocket, because one you get it down, it's just a matter of increasing or decreasing the amount of axis rotation by a little to get the reaction that you want/need.
Watch some Chris Barnes videos... probably one of the best example to see how it's done.
