Are we talking about any specific horn? For 'nino and soprano the BSS size small is great. For alto, tenor, and bari I've been happy with the Jazzlab Saxholder, but for bari I also like the Nobcor Gemini Ultimate harness, and I just picked up a Zappatini sax harness that has quickly become my favorite for bari, though I will say, the support rod seems maybe a little flimsy. That said, it's still the most comfortable and adjustable option I've found for bari.
