If you are planning on charging buy another ski.
I'm about 6'1" 175lbs and ride 189s in the trees no problem. Even though they measure 195ish they are much easier in tight trees than my 186 line prophets.
With the huge rocker and zero camber underfoot they smear and pivot really easily despite their size.
Another thing i have to mention is that you mount them at or near core center. I rode a pair mounted at +2 and they were a completely different ski. If you mount too far back and land back seat there isn't any stiffness behind your boot and you wheelie and loose a lot of control. Mine are mounted at core centre and im very happy with it.
