Ive skied ANTs, own JPs and own Pistols. I find the JPs to be a little more versatile, but only by a bit. The ANTs are actually more turny the the JPs, but the shorter length and massive tail on the JPs make them a little better in the trees. The JP is the best of the 3 switch. The ANTs kills the JPs and Pistols at speed, and destroy both in the crud. If you have 2nd pair of skis for the icy days/park/spring you are golden, if not you are still doing ok.
The only reason I got JPs over the ANTs was cause I got them brand new for $300. If I had a choice at the same price I would have bought ANTs at the time. But I'm good now, the ARGs take care of the speed, pow, and crub for me.
