It's hard to answer your questions cause guys here don't know much about your game. Speed, revrate, or even a video.
I'm guessing you had a knee injury? Thus, your speed is slow? If you're moving so far in/left and you run out of room, have you ever balled down?
My late teammate had knee issues and his speed went down to 12 to 13 mph. He was struggling so bad with reactive and urethane balls. The reactive balls made him move left and he was just O/U. Plus, he was battling cancer.....
Since His hands could fit my clear tire spare ball, I let him used it. BOOM 211 average for the last and final part of the season...sadly, he never returned after that summer...Bob made it happen using a ball type no one else used during leagues and he enjoyed his last few months of bowling....
