Do yourself a huge favor and get a harness. I use a BG that was given to me by a MUCH better saxophone player than I. My spine is much happier, and I can breathe better, too. They look really dorky, and also take some time to get used to, but the last time I used a traditional neck strap I couldn't imagine how I managed to use one for as many years as I did.
Also, it sounds like you're giving yourself some great ear training. Keep it up.
