My cruise on FL100 at 75% is 193 KTAS, which is exactly as
advertised. I use a straight O320, 160hp, and a fixed pitch prop. Cruise
using other hp should be proportional to cuberoot of power increase, i.e.
180hp should give the advertised cruise. You can throttle back and get
193KTAS with an O-360 and the same fuel flow as an O-320. Climb performance
differs more. Increasing hp by 12% gives more than 12% better climbrate. I
get 1200 fpm at gross and 3500ft and 120 KIAS, which corresponds to 1400 fpm
at SL.

Keeping the weight down does not only allow you to bring a fullsize
fying buddy, it also improves your performance quite a bit.

About the MK2 tail, I have flown both tails, and I cant say there is
any noticeable difference on the perceived stability.
