i have 2 twisted fury pearls and i looking for them to compliment each other. I was thinking one 60-4-30 but wasn't sure about the other. i wanted to be longer but smoother like 70-4-60 do u think it would be a big enough difference with surface adjustments i was going to put polish on second one wasn't sure on what grit to put underneath and leave the first at 400 grit rough.I also have twisted fury solid  drilled 35-3 1/2-30 and plan on getting a Maxxx zone drill 45-4-60.would this be a good arsenal to bowl on THS and a pba experience league?

I had two TFP's,one drilled 5x4.5 pin above grips and the other with the same layout but below grips,both were close to the same reaction.
if I would want to drill up another pair I would give one the rico treatment and layout the other 5x3.5 and adjust the covers 2K on the rico and polish up the other.

The harder I try the harder they fall
