Hi Cassp,
I also use 2 keyboards and the Quiklok M92 and agree that, though not the lightest, it folds easily and is the quickest to set up & take down. Definitely the most stable stand I have ever used and I wouldn't use any other now. Looks classy too compared with all the other stands I've seen. It took me a long time to choose which stand would be best for my needs and, fortunately, I'm happy that I made the right decision.
Best wishes,
