Replying to Hitting rails unnatural

I liked the thread before about the 270 on tips. Question tho, since I will be landing unnatural on the rail should I learn unnatural first? Any tips to make sliding unnatural easier? for some reason I lean back when popping onto the rail which is very strange considering I wakeboard and snowboard regular (left foot forward) so it seems I shouldnt have a problem leading with my left foot... Any tips? maybe I am pressing off one foot more than the other or something but I really wanna get my unnatural slides and 270s and switch 270s down this year...
