I tell you what bothered me the most was the rating the Mutant a bigger hooking ball than the Super Freak. By no means is the Mutant stronger than the Super Freak. Also, the Phenom Unleashed is not a ball that hooks more than the Phenom, however it certainly outhooks the Freak. The Crunch is a very good ball, but it does not cover as many boards as the FreakOut, maybe with it dull and the FreakOut polished to 2000grit. From what I have seen in my own experiences.....I would rate the balls you have listed in this order(balls I have not used, I will state I have not:
Phenom
SuperFreak
Phenom Unleashed
Mutant
Freak
FreakOut
Crunch
Triple Threat-used on a limited basis
Thrash
Crunchtime-have not used
Threat
Dryheat-have not used
In BTMs defense, I think that their rating system is supposed to be a starting point and not something that is written into stone.
