I have been throwing the Black Tester ball. It hooks more than the EPX T1. Similar length, very smooth, but more hook in the last half of the lane. Doesn't hook quite as much as my Action drilled the same way. Hits really good, have shot over 700 with it on wood house shot, when there has been enough oil (3 times). No cracking or anything, don't know what core it has. Think I heard something about spring release, but I could be wrong about that one.
