Replying to Pow ski choices atomic automatic

so i am 6'3 about 215 rode the 186 (i think) automatics, and i live in utah ride brighton. just trying to decide whether i  want these or not im not used to riding something with so little tail can i mount these a little farther up from the recommended spot or will it drastically change things. and i am alos probably going to get the 193 or whatever size it is. loved ridng these by the way

and i have ridden the bents and liked those to i just feel like i can charge harder with the automatics.
also any other ski choices something like these maybe that would be better to center mount?

and lol, i plan to just ride whatever with these pow, crud, trees, etc, any advise would be awesome. and best bindings ffor them as well would be aweesome.
