.lenconThey'll float just fine with all that Rocker and a 109 waist.
I think when I had mine they were center. Fun ski, just not durable, but I have heard surfaces durability is improving so that's good.
KravtZI mounted mine just back from the "progressive mount" location.
These skis have a crazy rocker but i promise you are some of the most fun skis I have ridden. They rip powder and float very very well as you can imagine with the rocker profile. They are my go to spring ski on the slush such a fun ski that float/surf around so well. I've had them on everything from east coast ice this year to 3 ft pow days at Squaw valley and they have been able to hold it down quite well.
Surprisingly pretty solid on groomers also. They can hold an edge much better than the rocker indicates and that was the biggest surprise for me. The faster you ski on these things they better they become. They do ski really short given the crazy rocker profile. But its pretty amazing to feel how the tips/tails engage when you get through some deep pow. They have some much pop in them.
I have the 189's and love them.
My only critique on the ski is I think there is a bit to much tail rocker. I know they are designed as a pow jib ski for the most part but I find myself wanting some more edge on the tail occasionally especially on crud.
But overall I would give these an 8/10. Such a fun ski you will lvoe them. I have attack 13's on mine and they rip.
