Not sure if this has been asked before - a quick search revealed nothing, so comments and opinion welcome. Has anyone got or used the now-available harness (or known as a sling?) for carrying their tuba (or Euphonium, etc) during marches instead of the traditional one leather strap? I'm thinking of the image attached kind of design. It looks to have several advantages - that is not pulling on one shoulder (straining) and easier to clip on and off whilst spreading the weight more evenly without giving yourself a hernia?! Do they work and are they any good in general? They appear to cost from about £50-80, any recommendations on makes, etc? Thanks all.
