Thanks, I actually gave a go to the Rubin for a while but it didn't satisfy me enough to justify the price... Planning to try a Brandoni Piccolo (which should be about the same size I think) and one of the newer 30 keys Paolo Soprani, once we can travel again here (currently restricted to 5km from the house in Ireland). I had a chat with a few friends who are touring regularly, both playing Saltarelle Clifden boxes, and they told me that they never had any issues to bring them as carry on on planes as long as they had priority boarding so that made me feel a bit safer about it too.
