As others have stated, surface is everything! I recently bagged to Brunswick pieces (Mastermind Genius and Melee Jab), and I didn't like box (500 Siar plus Royal Compound) finish on either one. For me, they both read too early and had muted movement down the lane that way. I took the Genius to 3000 Abralon and the Jab to 2000 + polish, and they have been great. Play with the surface until you find what you're looking for.
One observation I made is that it sounds like you're rev dominant (more revs than what your speed can necessarily handle). If that's the case, surface is going to be a bit tricky at times. Personally, I don't know if the suggestion of 4000 or 4000 plus polish is going to be the solution. That should make the ball cleaner up front and stronger down lane, but it sounds like you already have that covered with your Platinum. If that's the case, you may actually want to go with more surface. There is a cranker in our house who uses 500 grit (or sometimes even lower) on some very aggressive pieces (Hyper Cell, Asylum, etc) in order to intentionally bleed the ball off a bit. From there, he lets his revs do the trick of making the ball hook and hit, and he's doing a great job of it. Obviously, you'd have to play deep inside to do this, but it may be something else to consider. I see far too many high-rev guys and gals just keep going smoother and shinier, and that doesn't always get them the shape they want; it often just makes the ball longer and harder to control.
Keep us posted on what you try. Good luck to you!
