I see what your saying,
I guess what I'm trying to point out is that there are no structural rules for designing and building a stand. It's what looks good and appears strong and ultimatly is up to whoever is building it.
So in essence a "Professional" stand is still just a "home made" or "DIY" stand and always will be.
Thats all really..
