Domains are solid for carving on groomers but in the trees/bumps/ungroomed runs I have found that they just kind of throw you around because they are a softer ski. I think you will find the same dilemma with alphas because of the rocker but I have no experience with them so dont take my word for it.
It seems like the ar7s/recoils would perform better on an "all mountain" spectrum because they dont have as much flex and the recoils also have the "all terrain rocker" which speaks for itself. They are all great skis though, good luck with your choice you wont be disappointed!
