Jeffrevs,
I'll mention my ball choice, but first here's my comment on "control".
Control is the ability to have a ball do what you tell it to do. When you want it to arc smooth, it won't overreact. When you want to hit on it, the ball will react and turn the corner. When you want it to go straight (I don't mean 10 pin straight; I mean a tight line), it will go long but not through the breakpoint.
For my game, I'd expect "control" in a ball that meets this criteria:
Coverstock - mild resin, solid, 800 grit, cross-hatched
Core - Low to Medium-low RG, medium differential, symetrical
Drilling - 2 1/2" x 2 1/2" with weighthole on PAP
The drilling and core are for a fairly, early roll which gives me a good read of the lane but it isn't prone to roll-out due to the milder cover. When I increase speed and revs, the mild cover gives length while lower RG drill and core magnify my revs to give the ball some flip on clean backends. All in all its the right combination for me when the shot requires "control". But if the lanes a wide open, I put the ball away a get aggressive.
Now this is the combination for my game. I wouldn't recommend this combo to a lower rev stroker, but it works for me.
I think the key for you, or anyone else looking for "control", is to think about what combo will give you the ability to have a ball do what you tell it to do.
Good luck!
