I like to think of it as "airbrakes or no". But let's not open that
can of worms today.

That Depends...

I believe that the usual choices a

Men: external catheters, zip-lock baggies, plastic bottles, diapers

Women: diapers, awkward-looking funnels

And some folks wonder why there are so few women in our sport.

This might be TMI, but before a long flight I tape the zipper of a
zip-lock baggie so it's mostly closed, and then tape a PVC pipe elbow
fitting into the remaining opening. I prefer the heavy-duty freezer
baggies. The baggie is generally more conformal than a bottle, and the
elbow fitting helps solve the "uphill start" problem.

Some folks have elaborate overboard dump tubes that they extend out of
the belly of their glider so that they can pour overboard without
getting pee on the glider. This is more than an aesthetic concern,
since the pee is corrosive and often gets drawn into the landing gear
well where it can corrode the metal undercarriage parts.
