That's cool! I totally did not mean to offend and am sorry if I did. I'm pretty sure I'm a downstream player though. I've never tried to permanently change to upstream, but during the beginning of the semester, my teacher tried to get me to play upstream. It did not work out. So, I just kept on working hard with my downstream playing. My playing is not great at the moment, but I'm still recovering from an embouchure change in July. It's getting more fun as I get range and technique back, and I can see what you're saying about double C's being fun. So those are my thoughts, and I appreciate your comments too.
