15", 16", 17" AAX crashes

OR

15" AAX, and 16" and 17" AAXplosion since they don't have the AAX plosion in 15"

i just wanted to know basically what would be a better set up for rock and punk type music and if theres a big difference between them. i even went to the store and banged on a few aax and aaxplosion cymbals but i still can't make up my mind.

Thanks a lot
