JJ, I agree with you and defer to your experience. However, I'd be
concerned
with tying down the cuffs from the front only. The spar being further back,
wouldn't there be risk of the cuff exerting too much downward pressure on
the unsupported leading edge of the wing?

Yes, but that would (could) exert undue pressure on the trailing edge
(ailerons & flaps)
Definitely use a wing stand under the spar with a wide padded area.
The dinky one that came with your Cobra trailer isn't wide enough.



I, and a few others I've seen, will often survey the ramp before an incoming
storm, checking tie-downs and trying to fix those that look shaky. People
that leave their gliders out during real blows are braver than me.

Yep, the last one I saw had two G-103's break loose and one slid up-
side-down into another bird. An intense discussion then ensued about
inadequate tie-downs. Finally a local judge ruled that it had been an
act of nature and the Hit'er didn't owe the Hit'ee any compensation. I
picked it up on the salvage market and she's flying today. BTW, next
winters project is a Puchacz that experienced a sage-brush landing at
Minden. The instructior (smallish gal) pulled the plug at 1000' to
test her student's (big guy) rope-break abilities. An intense
discussion then ensued about which runway would be most appropriate
(left back to 30 or right to 16). They fought and finally nestled (not
so gently) into the sagebrush about halfway between the two runways.
Bad spiral broken boom, but I just found a good rear-end from a spun-
in Puch, a little cut & paste and she'll live to fly again!
