I like T5's and CPI's over the ones you listed.. The T5's hit is hard as hell, and have a good top end pull, all in all the make VERY good power. CPI on the other hand has a bit smoother hit, and pulls to the freakin moon! The make awsome power up top, but kind of lack the grunt down low like Toomey has.
Out of the ones you listed, my vote goes Pro Circuit
