charlest,
I cannot speak of the phenom unleashed because I have not thrown it, but each of the previously listed balls are different, primarily beacause of the core.
The Mutant is the stronger at the pins out of the it, the super freak and the phenom. Of the 3, the super freak rolls up much sooner, probably 3-5ft sooner. The Phenom gets far more length than the Mutant, with a more angular backend reaction(but you will definately cover more boards).
I have 2 Phenoms, and decided to try something different on one from the other. The first one I have drilled with the pin drilled leverage and MB 5 inches from PAP. The second is drilled with about a 4 in pin and 3 in MB. The first one gets down the lane much further, and the second rolls up very soon and is certainly more of an oiler.
Every one has "hook monster" on their mind when they see each of these balls, but a simple adjustment in drilling(maybe placing the MB in your track) can make these balls very playable without a coverstock adjustment.
I put a coat of ProTRACKtion on one of my Mutants, and it hooked about 8 boards less than the weaker of the 2 Phenoms. So these balls are very playable, extremely versatile. Do not get me wrong, you are not going to use these balls on dry lanes by any means. But your normal league shot with oil inside will keep you being able to use them, atleast during the first 2 games.
example----I drilled a phenom with 3 in pin and 3.5 in MB for a 68 yr old guy that is a pretty good friend of mine. He hits the ball pretty well, but only has about 13.5-14.5 ball speed. He can use this ball on just about any condition except when the heads are fried or the backends are REALLY hooking.
