Abell straight head joint for Prima Sankyo Alto Flute

I have a Prima Sankyo alto flute with the curved head joint.

I like the curved head joint for ergonomic reasons. However, I understand that the third octave is typically sharp with the curved head joint (as is mine) and is better in tune with a straight head joint.

I did a bit of research and heard that the Chris Abell straight wooden head joint sounds really great on alto flute.

Does anyone have any experience with a Chris Abell straight wooden head joint on alto flute, especially a Prima Sankyo alto flute?

Thanks,

Mark
