I break it down like this.

Rev dominant players benefit most from 2 piece urethanes like Black Hammer, Purple Hammer, Fever Pitch because their higher revrates can get these balls to continue stronger off of the spot.

Lower rev players that typically play right of 10 can benefit more from the urethane with more aggressive cores north of .040 diff. They offer more flare midlane so they get into motion a bit sooner. It makes it easier to miss left and still stay high flush instead of going bucket due to the puddle inside.

Tweeners and lower rev players that have more of a natural "bend" in their ball path, could benefit more from the high flare, assymetric urethane offerings like Black Widow Urethane, Hot Cell, and upcoming Honey Badger U.

Your mileage may vary

Ive got 2 IQ Tour Reds that i throw pretty much everywhere if i can. One is dull and pin next to ring, cg stacked. My other is a polished pin above bridge, cg palm. These work great off each other and i know how to move and when to change basically everywhere i go, thats when i can start with them. FYI, the IQ Red are an Int'l ball, U1S with the Centrepetal core like the IQ has.

I think I am somewhere in Kyle troup range of speed and revs.

then yeah, like DP3 said, you may wanna look at the hot cell, black widow urethane or the new urethane badger coming out
