I use a Neotech sling on both alto and tenor, and would probably do the same if I played a bari. If you are at all vain, a harness will somehow over-emphasise any, erm, thickening at the waist like what I've got 🙁
I must try the Rogerb sling method - is it comfortable, Roger? I don't have any arthritis, but sometimes get a strange aching between the shoulders, as well as being prone to (and sometimes prone due to) lower back problems.
All these aches and pains, I'm starting to turn into old git here :whistle:
Cheers, Bob
