This technique is hardly limited to omnis, in fact when Klas originally
talked about it we were talking about parabolics.
I've been making a lot of use of this technique. Seven feet I can do
hand held, but to go higher requires support. I have some high mic
stands, but they are not as high as light stands. You can get really
high with light stands, the one in the photos above is about 15'. I've
recently obtained a Bogan 3076 light stand which will do 17'. It's
lighter than the other stand and reduces to a shorter length. Aluminum
makes it reasonably light, but that's a mixed blessing. It's only rated
at carrying 3 lbs, and I'd not try using it in any kind of wind. The 15'
stand I've used in a fair breeze. It's more robust.

Many of my recent sound samples have been recorded with the SASS on the
high tripod.
Stands above those heights tend to get heavy and awkward to set up. But,
the height I'm getting seems to take care of most of the clutter.
Light stands have a standard fitting that's got a short 1/4" thread at
the top. I use a machined adapter that slips over the whole fitting, you
can see the adapter in my M/S page:

Not only do you get away from the ground clutter, which makes sounds
cleaner, but with directional mics you have another option. If you get a
directional mic up high and point it down at your subject, you will pick
up less distant unwanted noise.
If working where some callers are close, getting the mic high will help
to reduce the sound overload from them and allow you to record more
distant subjects.

I'd think this would have problems in day to day use with wind.

Look into the Sennheiser 1000 series digital wireless system. It
transmits a 44khz 16bit digital signal, avoiding the analog problems.
I have a couple of those (takes two for stereo). For my system they have
the problem that their transmitters don't provide phantom power, so I
have to have that between them and the mics as a minimum. I've got all
the pieces to do it, just have to find the time to set it all up.
