You are correct that it does flare quite a bit still. (That's the nature of asymmetric equipment I believe)
I actually rarely see truly heavy, heavy oil, and when I do I can just move right, keep my hand up the back of the ball more, and slow down. I don't need to hook it, I just need to create entry angle and roll. I was throwing it damn near straight the other day on the Shark playing outside, but hey, it worked. I use the Cell for anything from medium conditions when there's carrydown all the way up to heavy oil. The ball doesn't overreact in the midlane with this drill, but also doesn't rely on clean backends to make its move. That's the exact reaction I wanted from it. I need to bring my camera with me to the lanes on a few different conditions so I can show people the kind of reaction it gives me.
