I had a shoulder strap, before I could find a neck strap that was better suited to me. My first neck strap needed to be so tight to get the sax to my mouth, that I was being strangled by it, and it was constricting the blood flow through the sides of my neck! I tried a shoulder strap, but found the sax kep sliding down to my side.
I now have a NeoTech neck strap that I reduced the length of by unpicking the stiches, shortening appropriately and re-sewing.
Rogerb! I found the Cebulla straps available in the U.S. at Music Medic - http://www.musicmedic.com/catalog/products/strp-100.html Invented by a yoga instructor - the reviews are great - I may try this instead of the shoulder strap. Thanks!
