I've a heavy-ish tenor and found my neck sling quite uncomfortable. There are a number of harness's on the market but decided to go with the modestly priced Thomann version. It transfers the load to my back and shoulders and completely takes the strain off my neck. A bit fiddly to put on and adjust at first but once you get used to it, not a problem, so I wouldn't mark it down for that. Very happy with my choice.
