What type of surface are you bowling on? Wood, guardian heads, synthetic etc..
I am sure the pattern will a little different, especially if bowling with different bowlers. Try starting further right, you are really traping yourself by playing too deep to start with. Ideally you want to make a "burn" spot on the lane, and bouce it off there to create some area right.
Another option would after watching the ball check up early, switch to a ball with a harder cover.
