The other thing that can work is running your fancy primary vario off pitot + static with "electronic" compensation and leave the probe for your mechanical. In this case, the pitot and static need to be *really* good (fin mount triple probe) and not shared with mechanical instruments.

That is my approach - my SN10 gets fed by a nice Ilec TE probe, and my other vario is the really nice electronic TE Westerboer 1020, which works just fine using the aircraft pitot and vario statics.

No concerns with TE probe leaks, cross talk, etc...

Mechanical varios are so last century....
