Hi, as the reed is as small, in relation to the lip, you will get big difference if you up or down in reed strength. If you go for old jazz style mpc a smaller opening and harder reed will be my tip. If you want a edgier sound and use baffled mpc you should try bigger opening and softer reed. As the soprano is less forgiving it will be more sencitive to the strength of the reed. If you gig with only the soprano you need to bring a number of reeds on stage as your moiste and the humidity of the room will change the responce. By the way if you been playing clarinet, you have to "unlearned" how to hold a straight instrument. Think 45 degrees and and you will drop to 60 or us a curved neck. Play on, Cal
