I found the same problem so moved way to the left on the approach so I could try a totally new oil line with limited success. It also opened up the possibility of losing a few into the gutter, which I hate.  My idea was to stay on the oil as long as possible to create a deeper skid before the ball hooked into the pocket.

However, I have discovered that the longest part of the oil pattern is down the middle, so I will now try coming inside a little further - try it yourself in practice - bowl a couple straight down the middle and you will see a lot less boards covered. 

Armed with this knowledge, I will experiment with new lines to the pocket.

I don't know if you already knew all this or not, but hope it helps you.
