I got linked from another forum pointing to the Hellbent Mounting thread

I am thinking of getting 2010 189cm HellBents with Griffon SchizoFrantic bindings. I am 6"3 and 190pounds, I was actually leaning towards the 179's but now i'm thinking 189's might be a bit better for landings airs, I guess they would ski hardpack slightly better too? I am also into tree skiing and the 189's (which measure 194cm!) might be a bit too long for tight trees... Can anybody share some insight for ski length here?

I am an advanced skier, not an expert - my current all mountain skis are Volkl Mantra 08's, 184cm. They are pretty sweet, but super stiff and not poppy and fun, which everyone seems to say about the hellbents. I am also looking to start skiing more drops jumps and BC booters, as well as riding switch. Based on what I have read the hellbents are probably the best option. I will be using this ski mainly for Niseko, Japan - which is one of the snowiest resorts on the planet. I am thinking about purchasing the ones in the ebay listing I linked above. Does anybody know anything about Griffon Schizo bindings? It seems they are adjustable, so I would probably mount them at +6 which would allow true center for the not so deep days/ and could take it back to 3 - I probably wouldn't tho.

One last thing - everyone says that having mad float in powder is a good thing, I found on super deep days that I would sink a bit and the powder would be up to my theighs, this was a pretty amazing feeling, would I get this feeling with fat pow skis? Does it still feel as good? Is it harder to get face shots?

Sorry if this wasn't very clear - I just don't have long before my trip and i'm trying to see if its worth getting these skis...

Thanks guys!
