I was the same way with my cell.. Where did you put the MB. I put mine way too strong for my pap , tilt and revs... lower pin with a 45 deg mb.. and the cover is really strong..
The ball never wanted to come back and had zero backend or recovery..
I really think it was the drilling that made the ball not work for me. I should have just drilled it how I normally drill my stuff and let the cell's charateristics take over.. instead of trying to help them..
