Onto instruments. Sharp control movements, AH dancing about. Cold and gloomy. Work at staying in the lift.
The one and only time I psyched myself up enough to do a cloud climb, my (ancient, secondhand....) AH did a slow 360 degree roll just at cloudbase!
The airbrakes came out, and I never had the nerve to try it again in my glider. Also never had the nerve to try it in a club glider with just a turn and slip....
Note to any IMC pilots - don't ever fly through a fluffy cumulus cloud, 'cos there could be half a dozen gliders inside it!
