JJ's are a good ski, not overly playful, but they handle the whole mountain really well, from pow to crud to groomers they got your back.
The Sir Francis Bacon would be my last choice ever, it is still really playful and stuff, but no rocker and there are other skis that would work way better. My friend chose those over the Bentchetlers and is now kicking himself in the butt.
When I rode the Obsethed I was really unimpressed, to me it felt really dead. Read the threads and a buncha people agree with me and a bunch of people think its gods gift to man kind. I dunno, the way I see it, Seth Morrison designed a ski to straight line alaska so thats what it feels like it should be doing all the time, maybe a little to solid feeling if you you know what I mean?
Some people were mentioning the EP Pro and Hellbents, they are definitely playful but they don't have the cambered underfoot which makes them a little sketchy on groomers and crud, cause you have like 50cm of ski actually touching the ground... They are more of a deep pow, BC Jibbin kind of ski.
I ski the Atomic Bentchetlers and Love them! Similar to the JJ's but a little softer, they take on anything with relative ease. They are soft, but really snappy which is nice cause its not like you have a wet noodle under your foot. They come in 183, my dimensions are similar to you, 6'2" 170lbs and they seem really nice on me. If you are a strong skier the length won't be bad at all. If you are worried about the length maybe look at the Atomic Blog, its basically a mini version on the Chetlers, 110 underfoot instead of 123. It comes in a 177 so that could be a really good option as well.
Hopefully this helps!!
