Bruiser is the overall stronger ball. It does not only have much more flare potential, compared to the AS, but also a lower RG core. A polished or Rough Buff surface Wizard might come close to the Bruiser, but the BVP core still has a higher RG and will be a tad less "rolly" than the Bruiser.

If you want a really juiced-up alternative, check out MoRich's Awesome Finish. Also polished PK18, but coupled with a core from hell that makes a true high performance piece for medium conditions out of it. IMHO good for the same conditiosn as the Bruiser, but with much more juice overall.

Be careful with the MO and make SURE you drill it for EXACTLY what you want, otherwise you will have a turd on your hands.  I can't tell you how many pissed off customers we had with that ball.  It was an awesome piece for me, but I wasn't affraid to go coast to coast with it, those with less speed/hand were struggling to make it work on a house shot.  Personally I thought it was sick, just drill it for what YOU want, not what the driller thinks, pick it off the sheet, match to your game and expect to get that.
