I think the HH medium is probably closer to a Fibracell 3. The HH medium soft is somewhere between a 2 and a 2.5.
No break in required. They just play. I use a MS Carbon Fiberreed, and also Fibracell 2.5 on bari and find them similar. The HH may be just a touch softer. It's a bit hard to tell because the HH reeds are so free blowing. The M should be close to a 3.Is there a break in period with Harry Hartman Fibereed Carbon reeds? Also, I use a 3 Fibracell on bari. Would that be like a M Fibereed?
