Hey. For some reason my current reeds will never work for me. i play La Voz MS on a Berg Larsen sms 105/2. Every time I buy a new box they all are too stuffy and hard for me, no one plays good. I have to play it for like 3weeks until it finally plays ok and then it dies like 2 days after. I dont think I have the wrong reed strength cus like I said after a while it plays ok but in like 3 weeks it plays horrible. Is this the same for you and if not do you have a solution? Thanks.
