Gilles,
You made a great choice. I use the 76S in my 1-26 and bring it with me for
use in club ships. I recommend the Ram Mounts and especially the suction cup
for use in different ships or driving for that matter.

The glide ratio is a bit twitchy, but if you are on a straight run it gives you
a basic idea. I find I use the ground speed alot to judge the winds. The
simple arrow to home or your next waypoint is a great indicator

If you fly in two seaters, and the back seat is lacking instruments, it's a
great back up.

Lastly, I've had some contact with Garmins tech supports, and there were hints
of more soaring/hang gliding software updates to come.
