In my previous life I started with gliders but never got the PPL-C. After earning the PPL-A I also got the PPL-B but never used it much to fly motorgliders solo.
To be honest my fantasy is about real gliders – no engine – and it may take few years until I actuall give it a try. So it’s just a memory lane thing and I’m just being curious. Flying the SR22 IFR will be kind of “work” and I may start dreaming about just flying more and more :-)))
Do you still have the TMG class rating in your PPL?
There are some real advanced TMG’s like the Stemme S10 which has a maximum glide ratio of 50.
The Stemme S10 is not a TMG.
The FCL regulation says
“Touring Motor Glider” (TMG) means a specific class of powered sailplane having an integrally mounted, non-retractable engine and a non-retractable propeller. It shall be capable of taking off and climbing under its own power according to its flight manual.
The Stemme propeller is retractable
So you definitely need a Sailplane licence to fly a Stemme S10
