fittings since another person is not risking a hernia while holding
the wing, more freedom at the soaring site because I don't need
another person to rig or de-rig.

I use the Cobra system on gravel, dirt, and pavement. *Works very well

and have to say that i prefer the manual crank for elevation control

However, that is only a matter of taste. *Both work great.

I built my own one-man wing dolly using a VW tower jack for vertical
adjustments. A wing is a LOT lighter than a VW so I cut the crank
down to 5" which still lifts the wing with finger pressure. I
probably could have used a knob instead of the crank.

I considered the gas strut and even went as far as to buy one with 100
Lbs force, but decided to stick with the VW jack. I thought I needed
to lock the height at an exact value. Anybody want to buy a 100Lb gas
strut?
