Roue cyr's come in different sizes and thicknesses and metals.
Aluminium or steel...
if they're steel the diameter of the tube is generally thinner, as steel is stronger. My one is ali and the tube is about the same thickness as scaffolding tube.
You want a 5/6 section roue, as 3 is too little. The sections are too big to fit in any normal bag.
finally as to height, daniel cyr would say that (I think) the internal diameter be your height plus your fist, plus a couple of centimeters. But yeah different heights are good for different things, but that the height that's averagely good for stuff.
Like big roue good for the waltz and cartwheels I think, small roue, good for coin spin. That's what I seem to recall.
