If the lifting force exactly matched the weight of the glider then, in
still air, wouldn't the glider not lose altitude? Or are you saying
that the sink rate of the glider is cause by drag?

Yes, I have enjoyed slower-flying thermal-working too. It's lots of fun.

My curiosity about wing loading and climb rate really is limited to non-thermalling, non-turning flight. I was wondering about the possible relationship of wing loading to lifting force. Likely an unrealistic circumstance in actual flying though. Just a curiosity.
Well, on a good soaring day, about 70-80% of the flight is non-thermalling, non-turning flight.
And the lifting force always matches the weight of the glider, regardless of wing loading.
