YRA-302bIII v YRA-28b?

I’m sure that there are enough alto recorder players out there, so I know that the 300/400 series of alto recorders are a step up from the YRA-28b, but I kind of wonder how different the YRA-302bIII will feel. For context, I am an experienced wind player (four years of experience playing bass clarinet) & I’ve been playing a lot of Alto Recorder recently after my brother bought one on a whim. The YRA-28b (the beginner model) has a straight airway & a shorter labium than the 300 series & I personally feel like it’s too free blowing—which is apparently rectified by a curved airway, giving users more resistance than straight airways. I hope that the 302bIII improves my recorder playing experience—guess we’ll see in two days.
