Have you tried moving your feet and your target? Maybe the 5 board isn't where the shot is for that ball. The Second Dimension's strong cover needs oil to get down the lane and retain energy for the back part of the lane, and usually there isn't a whole lot of oil outside of 5 on most league shots.
Also, as always, video would help immensely. If you can't get the Second Dimension to hook, you're either doing something very wrong, or you're just playing the lanes wrong and exaggerating how bad the problem is. For reference, the Second Dimension will cover more boards than anything else in my bag on a medium to medium-heavy oil pattern, and it's not even drilled very strong. I did, however, have to change the cover to get it to handle any oil. The factory polish was too high gloss, so I sanded it with 2000 abralon then applied polish myself just by hand, I didn't use a spinner. Much more midlane read now.
