I have decided to take the plunge and try out a poponcini, I am wondering about the different mouthpieces Harmony A, 1, 2, 3 - is A the softest, and how much difference between A &1? I am going to have to order online as there is nobody locally who sells these. Going for as soft as possible.
You should reach out to Brad from Equusport (CA based I believe). Brilliant for bit help and they carry the biggest selection of Popocini I’ve seen stateside.
