The tricky part about the Shark can also be the lane surface itself. How much friction's naturally present inside 2nd arrow at that particular bowling center can make a huge difference in how the pattern plays. There also can be variances in what volume of oil is laid down, and how well-stripped the lanes are. If you are going to be playing inside, I agree that you need to use something that responds quickly to friction in order to create entry angle.
Unlike you, I have a lower rev rate. Therefore, I have little margin for error and poor carry playing inside on the Shark, especially once the carrydown hits. My best luck on the Shark in my PBA Experience league this summer was taking a pin-down Cell at 1000 abralon and moving right. I played the lanes almost identical to how Norm Duke tackled the Shark pattern in
this video, crossing at about 7 or 8 at the arrows and basically pointing it toward the headpin. My carry was surprisingly good, but I had to be accurate. It kept me in the 180-220 range each game, which was good enough to win the games in my league, so that's fine by me.
So the moral of the story? There's more than one option, so don't be afraid to try different things. Don't always go by how the pattern is "supposed" to be played.
