I think it’s interesting that Sarah Jeffery says that it is easier to play the inexpensive plastic instrument than the higher priced wooden one, but that the wooden one is more flexible. This kind of fits in with what I think about the Bernolin with regard to the high notes. It is easier to play a plastic recorder’s high notes than the Bernolin, IMHO. But the Bernolin is MUCH more flexible on all notes and once you get the hang of playing the high notes is also more flexible on them (but it takes some practice and I do wish they would “speak” more easily).
I’ve heard that they have improved Moeck Rottenburg recorders in recent years. But just FYI, I have several older Moeck maple Rottenburgs and while they are pretty nice instruments, they do not sound nearly as good as the Bernolin. I mean, the Bernolin was a revelation to me, sound-wise. So you cannot spend say $300 – $800 (depending on the type of wood) on a mass-produced wooden recorder and hope to get one that sounds as good as something like the Bernolon resin. Just my opinion.
