I am 5'11 230 and took my buddy up who is 6'4 270. Should to shoulder it was snug, but we had room for sure. I'm not into acro, the nine is an epic cross country machine!
Pete,
Not sure it is a typo or what, but 800 fpm with an IO360 seems a bit anemic.

Depending on the OAT's, with a fixed pitch prop, that might be a good number.

That’s with a 110 knot climb out at 1850 pounds. I get well over 1k if I pitch up to 100.

11.5K, 5.7 gph, prop = 2200 rpm is a sweet spot for me.
