I recently switched to a curved Yanagisawa soprano and love it. Right now I am struggling with the right mouthpiece and reed comb for it. All my gigs will be contemporary jazz (Warren Hill, Sanborn, Albright, etc.). I have a Runyon 6 which seems a little closed and hard to keep in tune. I bout a Runyon 8 and it plays really stuffy, nothing like the 6. I bought a Yanagisaw metal 7 and it seems stuffy as well. Do I maybe want to try a Dukoff or maybe a Selmer soloist?
