Replying to Park skis for Old Guy

I'm trying to learn some park @ 47 and have been skiing some Line Blend 171's; I'm 5'8, 165lb, strong legs. Will be skiing mostly out west. I have other skis so I'm looking for whatever will help me learn fastest (and be fun). I'm a beginner butterer, terrible on rails (can't even have fun yet) and like jumps a lot but skill level is low; I have done some decent straight air, ugly 180's, and really ugly 360's.

I like the blends a lot, but I would like to try something new that'll help speed up my rotations and jibbing, and generally help me learn park.

B-Dog 172?

Thanks!
