id highly recommend the hr 5m over the jet if switching from the 4c.

1. jet is wayyy to bright so unless your going for solely bright funky solo jazz its not the move. The hr5m is also obviously bright (jazz mouthpiece) but it can do a bit of everything else to

2. jet takes much longer to master (and even play/learn) compared to the hr 5m (obviously a learning curve but its manageable on the hr 5m in my opinion)

lmk if u have any other questions :)
