If you have 2 people you don't need a one man assembly dolly, unless
one is a spectator.

I bought an early model Wing Rigger. It's not perfect and there have
been several improvements since I bought mine, but I can rig solo with
less back strain than with a helper and it only takes a couple of
minutes longer than with an experienced person on the tip. It is
quicker and far less risk of damage than having an inexperienced
person on the tip. I also find I am in less of a hurry to clean and
grease the spar bushings as no one has to hold anything.

I still find it quicker and more convenient to de-rig with an
experienced helper but using Wing Rigger to derig is not a problem.
It's just a preferance.

BTW in my opinion the gas spring is completely unnecessary as height
adjustments are easier made with the fuselage dolly jack while
watching the spar bushing alignment (Cobra hydraulic jack). I set the
height of the wing saddle the same every time and very very seldom
have to change it.

Lateral positioning of the wing is done by pulling on a strap to drag
the main dolly wheels sideways. That is actually much easier to do on
dirt than on a paved surface. Getting the alignment right first
attempt is best. I once got both wings on with no lateral adjustment
of either wing but it's seldom I'm that good. With experience you
should only have to shift the dolly a few inches after inserting each
spar.

If you go for a used Wing Rigger be sure to get the right size saddle
for your wings, there have been some changes.
