hello. i am an ex professional musician and am considering the purchase of a cheap sopranino to play with my son, who is learning the alto. i played mostly soprano back when and have owned a mark v1, sa series 1, yamaha 62, buffet s1. could anyone with experience or an opinion give me input regarding the pros and cons of the yani copies over the selmer copies, fingering wise/comfort/tuning or anything helpful. i have enjoyed reading this site and looking forward to any inform i might glean. thanks for your time.
