Hi Seg, I have a couple of Tagg's and I think that you are right in your concern, if you are thinking about the instrument
being mounted at a height for standing; playing in that way can feel a little unstable even dangerously so if not mounted on a very strongly based stand, say a tom stand instead of
a cymbal stand. Didgeridoo stands all seem to be mods of other stands anyway and not any stronger than a cymbol stand, just cut for height.
Before the Tagg I built a holder for the Stick out of an old acoustic guitar
set upon a low backed guitar stand which also could accommodate a small practice amp.
But to make it strong enough I needed to bolt the Stick to the body
. Not an ideal setup 
. This is what lead me to the Tagg via Gene in the first place. But because of the unstable aspect I am still more inclined to use the guitar body as I can grab it with my knees but still have more freedom
to move my body without the Stick itself moving. I have likened this to a vertical piano that enables you to 'climb' and descend through chord shape and musical phrasing with a different kind of ease than if the instrument is attached to the body via the belt hook or even the Lap Dawg.
The next experiment for me would be to attach a Tagg to an old cello body, which I have. A very cheap Chinese Cello, small amp included, but a more substantial one and also the larger body to stand or sit behind. When I find the time
...I don't know if that helps but I do think that the Tagg is great for what it is and it is also very well
made. Can you make something that will work? Of course. Thanks for keeping this thread alive
