I am trying to understand the differences between the beak profiles of STMs over the years. I have played a few No USA STMs which seem to have a smaller profile than the Florida USA STM replicas I have played (Phil Tone Tribute, Falcon Florida). I find the slightly larger profiles of these replicas a bit more comfortable, and am wondering whether the originals from the Florida USA period also had larger beaks. The modern STMs also seem to have larger beak profiles.
