Replying to Asterisk Knee Braces

im 6'2 and 150 pounds and i have a torn ACL and miniscus left over from last season. i was skiing at CB today where we had 9 inches of new and i tweaked it for about the 5th time since i did it. this has brought to my attention that i need to do something to get through the season. the thing that i am realy interested in is the asterisk knee brace. so my question to you is if i get these are they going to work well for me. i like to ride park and have been told there bad for that. i also ride in rampages and am having trouble with the bottom of the brace clearing the top of my boot. i tried them on today and they were realy nice but i want to know what you think? also, do you think that it will be adjustable enough to clear the top of the boot?
