Replying to Magic J / Bentchetler pow ski sizing

Hey guys,
I demoed the 190 Magic J last weekend in Mammoth in good snow and loved them. I'm looking to buy my first pow specific ski. I'm currently riding moment PB&Js and plan on continuing to ride them when there is little to no fresh snow on the hill. I'm only 5'8" 165... do you think the 180 would be a better match (they didn't have them to try) or does 190 sound ok?

Also, the only other ski that I've had my eye on is the Bent Chetler. Are they similar at all to the Magic Js? I'm pretty sure I want rocker/camber/rocker because it's what I'm used to, but also to make it easier to get back to the lift through the more tracked out stuff.

It'd be great to hear any input on these particular skis or other recommendations also. Thanks in advance
