I'm 5'11, 225, my 9.12s are 160. I doubt at my weight that 150 would be the best, but a guy at my local hill got the 150s and loves them(he is 6'0,about 175). If you like quick turning, hard carves, stability this is a great ski. It works very well at slow speed, but really shines when you crank them.
One area that should be addressed, the tails!!!! If you get in the back seat you will pay for it!!!!! Stay centered and they are a blast.
