In my Solo 2350 powered 29E, I find it quite possible to recognize a thermal even though everything is vibrating and the vario readout is very nervous. I try to circle with a constant speed and if the vario constantly is positive and I still have the impression (seat of the pants input) I'm in a thermal after 2 or 3 turns, I shut off the engine.

Of course only if situation (altitude, landout situation) permits.

With my Ventus cM, I do exactly the same. I judge the quality of the thermal by the reading of the integrator value (and my seat pans); the TE probe sits in the propwash (haven't seen the necessity for a pneumatic switch during the last 10 years...) which makes the realtime vario reading fairly useless.
