I have since flown my 170 in a number of different gaggles with
pilots I have known for years, in both good and turbulent conditions. What has
been a remarkable development for me is that I have been enjoying the very same
air I would have formerly loathed. Now I listen to other pilots complain about
how turbulent and un-fun the turbulence was, while I keep (mostly) quiet about
how great the air felt to me.

In Summary

My Sport 3 170 will not keep up on glide with my 155 and falls short in
penetration, as speed required increases. My 170 has a noticeably slower minimum
useable airspeed, as well as better sink rate, but only when I fly the glider
more slowly, which I often forget to do. If I try to fly my 170 at 155 or T2C
144 speeds, I find myself with too much wing and at a disadvantage. I have been
altering my approach and mindset to keep the advantage. I am always at an
advantage on my 170 in turbulence, plus I experience more favorable handling and
tracking most or all of the time. I can land my 170 easier and with better glide
path control by entering downwind leg at zero VG, with body upright and legs
spread. It comes down steeplywithout excess speed, and the flare window is very
long. The 170 is somewhat heavier and at the limit of what I can carry without
assistance, where the 155 is much easier for me to deal with logistically.
