Disadvantages of CG hooks are overblown.

Have launched AS-W20 (many times), Libelle, Std. Cirrus, DG, LS-4 and
likely others with CG hook and tip skids with no wingrunner. Have
towed many as well.

A method that has worked for me in the past.

Assess situation. Deside at what point you will release if it is not
working out, what the obstacles are on the upwind side of the runway,
how "up" you are mentally for this, and risk / benefit analysis.
Decide before pushing out / rigging if it is worth the risk today.

1) Put a/c on downwind side of runway centerline to allow for max
possible
amount of lateral drift toward Xwind and dragging wingtip. Not on
the
absolute downwind edge, but downwind of centerline. How much is a
judgement call.

2) Put upwind wing on ground. It will come up quickest in this
attitude.

3) Point aircraft "slightly" downwind. "Slightly" is a function of
intensity
of Xwind, wind velocity in general, a/c handling characteristics,
and
ground surface conditions. Obviously, more downwind heading in
larger
X-wind components and softer ground surface. Less for hard
surface, less
X-wind, and greater headwind.

4) Hold full downwind ("up-wing") rudder BEFORE takeoff roll begins.
The goal
is to minimize any upwind / down-yaw yawing inertia you have to
overcome.
Getting ahead of the system by having full rudder in before the
roll begins
is a very powerful tool. It is much easier to remove rudder than
it is to
stop a yaw that has already begun.

5) Review where release handle is and at what point you will pull off
if wing
is not up, you begin to laterally leave the useful runway surface,
or you
do not have sufficient control authority to continue. I have
punched
off multiple times in ridge conditions back east (USA) in rough,
gusty 20+
kt Xwind before finally getting airborne. A good ridge day made
it
worth it and an excellent tow pilot (thanks Dad!), and some sage
advice
helped made it work.

5) Have tow plane take up slack, hold brakes, and apply T/O power.
Tuggie
should watch propwash behind him and not begin roll until propwash
has
reached glider - and hopefully for a second or 3 after that.

Crucial issue is to decide quickly if launch is not working out and
pull off before it builds up enough energy to bust airplane / hurt
you. One can always push back and try again.

Kiwi's in Omarama, NZ routinely retrieve fiberglass gliders
wingrunner-less from remote strip / fields by using sticks and rocks
to prop up wing. Have done it this way from a narrow strip and it
works fine as well.

Of course, all of this is "Dangerous", and R.A.S. Theorists will
likely tell you about all the crashes these procedures cause.

Pay your Money and Take Your Chances (Or Not).
