Jeff Bennett leaves Cambridge Aero Instruments

I believe the advice given by an English 2x World Champion is to have a
good, well compensated, leak free, simple, vario then spend the difference
on Aerotows.

Likewise most modern (Standard Class) gliders have a kink in the polar,
such that best speed to fly for almost any rate of climb is somewhere
around the kink. So there are in fact only two speeds to fly; at the kink
if you're comfy, best LD if you're in survival mode.

So for the original Discus (Dry) it's either 80kts or 50kts

The more I read about high end instruments, the less I regret not being
able to afford them.

I have asked a number of people to explain to me exactly what their
"super varios" do that a good basic vario and a decent PDA/software
setup does not do. I mean besides calculating to more decimal places.
Maybe I would understand if I flew a glider with more than two speeds....
