The fundamental problems of reducing the wrist angulation, making the Gs keys and footjoint easier to reach and reducing strain from weight and position have yet to be seriously addressed by the majority of manufacturers. Unfortunately, changing tradition is next to impossible. Flutist's are wary of change to the traditional flute design so that most innovations in the past 20 years have been well integrated or hidden from view. However, change is essential if any headway is to be made in reducing hand injuries. When choosing a flute players often let fashion and popularity rule over common sense.
Students feel that graduating to an inline, open hole model is a rite of passage.
So the long term consequences on the hands are ignored. Many players don't even realize it is an issue. Often, a customized or modified flute is considered inferior which implies a weakness in the flutist as well. Of course, this is not true. But the collective result is that most flute companies won't take chances on a product line that isn't already accepted by the majority of players.
