Replying to Bi Directional Skis

Ok, I'm brand new here, so hopefully I'm doing this in the right thread. I've been looking for some new park skis, (I ski 100% park) and I'm pretty sure I want a center mount due to the advantages offered in the park by them. I've done some research, and it seems that K2 has the only lineup in which skis are characterized with bi directional sidecuts. My question is, what other companies make bi directional skis, OR, what park skis will still ski well when center mounted. Thanks for your help.
