Ok I guess I can take some heat for my input into this discussion if I put my foot in it, so here goes

On new or revamped instrument installations my recommendations are as follows, for what its worth:-

use a primary vario / speed command of your choice all the major manufacturers have their good and bad features, but Oz built has its advantages when there's a problem, Mike has always got time to try and nut out the problems on the phone or email with glitches in the system. If you want to run a backup Vario, (and as Bruce says how often do you get total electrical failure) apart from club gliders where the gorillas (sic) have worked on them ! run a electric vario that compliments the primary vario, in which I mean most modern systems today run pressure transducers, and mixing pneumatic various which are flow technology with pressure T/X is asking for trouble, as there is going to be some interaction between the two varios, which could degrade the primary vario, the up side of fitting a modern electric vario is you will get a faster response instrument and audio vario as a bonus, and it will probably have its own back up battery pack, if you get one of these fabled total power failures. all for a very similar price to a "steam driven" vario with all the features listed, if you make the right choice (I'm trying very hard not to let my bias show here)

I guess there are a few things to consider when contemplating a total
electrical failure. The first is that in many hours and many kilometres I
have never had one, though I am quite fussy about how I set up and care
for
the whole system. The second is that with the B40/B400 you would have an
independently supplied averager/audio still running, and the third is that if you were flying a comp, you would now have no means of verification, so
you may as well go home anyway. I guess your point is that going home
might
be pretty difficult with nothing but an altimeter...
