In 30 years of XC gliding, I'd say I've actually had to rely on the
mechanical backup maybe 3 times when the electrics went south. Not
exactly a compelling reason, but we're creatures of habit.

I used exactly the same reasoning as Papa3, but fitted two electronic
varios. The main one is entirely dependent on the main glider battery.
The other normally runs off the main battery but also has a 9v PP3
strapped to its rear that can run it for 8-10 hours if the main battery
fails.

I do in fact glance at it for confirmation while hunting for thermals,
because it has a much faster response than my main vario and I also
prefer it when ridge running because, unlike my main vario, it makes
'sink' noises as well as 'climb' ones.
