I've torn both my ACL's and would recomend you stay with a longer-stiffer ski. I tried some motherships, and though I liked them, they were so short for me(a 6 ft. guy) that they really tweaked my IT bands(the tendon on the outside of your leg you didn't tear). You'll need a stable platform, not some mushy ski that you have to stear alot, you'll want to stand and rail on a stiffer, bigger ski. I'd recomend a XXX, BC Scratch, or a Pistol. I've used all three since I went under the knife and like all of them...good luck.
