Can't go wrong with the alphas. Pretty stiff underfoot, softer in the tips and tails, lots of camber, and the slightly rockered tips and tails make for easier buttering. One of my favorite park skis I've ridden.
well i would count out the el rey probably. the alpha 1 and le compte are more high performance i think.
after that, i think that it comes down to preference a little more. the alpha 1 is going to ski pretty differently from most other park skis so i would try it out first.
