I've tried several brands when building up my large rack, and Gibraltar is probably the most solid. Having said which the very idea of round pipes for a stage rack is simply wrong. Too easy to under-tighten and the clamps slip while playing, or over-tighten and the threads fail. Plus one tightening of a clamp and the area where it's been is dented and ugly. So these days I use this rack only in the studio, where I never have to move or change it, and for the stage it's Pearl with the square bars. But if you do have to have round pipes, go with Gibraltar. And do DEGREASE with alcohol or acetone the area where you will be putting your clamp, it will hold much better!
