Most people use heavy oilers early rolling dull balls on the Shark..
In my PBA league last summer I took a visionary green gargoyle , which is a medium oil ball at best.. it is drilled with the pin high up close to the VAL at 5.5 " to my pap.. this ball has the quickest transition and flip ever...
I had success with it on the shark.. just got the speed slow enough so it would read the backend.. hit 12 -10 at the end of the pattern and it was money..
even got away with some balls farther right.. as long as I kept it slow so it didn't blow through the break point..
polish a ball up and give it a try .. it might work.
