Powder ski tail question

Hello,

It's that time again, time to renew my ski arsenal. I'm not here to ask what ski I should buy (yet), I'm here to ask what kind of tails I should be looking for in my new skis.

I'm around 6'3'' tall and 185 lbs, if that matters.

For the last three seasons I've been rocking the first rockered Line Sir Francis Bacons, the 2010/11 model. As far as I know, they're somewhat softer and wider than the current Bacons. The only thing I don't like about them performance-wise is that the tails sometimes wash out under me after I build up speed in bumpy powder due to me skiing too backseat. I also find myself leaning very much forward when riding switch, despite the good amount of rocker in the tails. Both of these problems are most likely caused by the recommended binding mounting point of -6cm if I recall correctly, as opposed to the -2cm of the new Bacons.

I wouldn't want to get a ski with non-rockered tails, since I have also been enjoying fooling around riding switch in powder. Would mounting the bindings more forward to the -2cm mark (and the slightly stiffer new Bacons, in case I end up with them again) affect my tails washing out much, or do I have to sacrifice some switch riding performance and playfulness to get the stability I need on high-speed landings in powder by getting more traditional tails?

And I do indeed realise that it's also a question of getting used to not riding backseat, which I have learned relatively well, but with multiple high-speed bumps/jumps in a row, I tend to automatically lean back more, leading to my tails washing out, causing me to find myself on my back.

Thanks
