Replying to 4frnt MSP's vs. Pistol vs. Vicious

I am wondering if anyone has skied the 187 MSP's, the green 189 pistols and the 189 vicious. I have the green pistols, and ski them everyday, but I was thinking about some MSP's. I love the pistols, but wish they were slightly stiffer, and had just a little less sidecut. I skied the vicious and love them, it was as if they took the faults of the pistols and corrected them. My major problem with the pistols is the sidecut, I do not like hooking up the tail when I am in something steep, or the tail hooking me into a carve when I am in something tight with hacked up snow. The vicious are great because they have corrected this problem, the ski feels less hooky and I can break the tails free when I want to. I am wondering how the MSP's compare to these two skis, if anyone has ridden all three. I very rarely ski park, I just stick to the steeps, so how they spin is not much of an issue. If anyone has skied all of these, or the 187 MSP and 189 vicious, I would be stoked on some info.
