You can fly IMC (ie climb in thermals in cloud and straighten up on a
heading) on just a Bohli, ASI and slip ball, I have done so in the past to
prove the point. It is very high workload and taxed me near to the limit
and I have far more cloud flying experience in gliders than most pilots.

Then you could do it also by looking at gps track instead of compass. I have only enough IMC experience to not try that kind of stunt.
