Well I got myself a Jazzlab holder. I had found they make a XL model but couldn't find one in Canada. While I am happy with the regular model, I do wish I could have tried the XL. I'm a big fellow, 6'1" and 220#. The shoulder arms are comfortable but sometimes feel a little insecure, I would like them to wrap over and farther down my back. The Jazzlab is great for getting the saxophone away from your body without straining your thumbs. I have both a Neotech and BG harness which both if worn tight, jammed the sax against my body making it difficult to properly address the mouthpiece. If worn loose the sax slipped down creating the same mouthpiece alignment situation. Adjustment to the Jazzlab is very stiff, weaker hands may need some assistance to shape the shoulder arms. Use of a mirror to check fitting is a must.
Bottom line, highly recommend it. Neck pain completely eliminated.
