Yeah agree with you there Fran.. I had an Apex stand and I currently have the V-Stand, but the upper tier attachement doesn't work for me quite in the way I need, plus I do find it a little bit wobbly, but just a little , nothing like the Proel.

But when I started to accumulate pedals (of the multi variety, I found the cross bar (floor) got in the way when trying to place them when sitting to play.

The On-Stage one is the latest model, and the catalogue, and specs, from Onstage says the universal upper tier does fit to it, so I can only go on that.
