Replying to JO pros too soft?

so I've been thinking about getting a new pair of twins.

I weigh 205 lbs and im about 6'3" ish -- I'm interested in getting the JO pros as they've gotten pretty good reviews from what I've read but I've heard their pretty soft.  For a skier of my weight, is there a point where they might be too soft for me??  Currently I'm skiing on a pair of Elan MO2 rails which are my first and only twins and I know they are a pretty solid ski.

Also, I'd be using the JO pros on groomers and shit too as where I'm from there isn't much of a park.  So I'm also asking where should I mount the bindings?  BTW I don't have much choice of twin where I'm from as I live at some shit hole in Ontario lol.  Anyways i just need some good feedback as I'm fairly new to twins and not up to speed on everything about them.
