I saw the answer to this question awhile ago, I can't remember how long exactly; I think I read it here, or perhaps on another music forum I can't remember how to get to...well, you get the idea. I searched the forum here, and can't find what I remember reading.
Anyway, here's the question.
Which whistles have a nice bright tone outside in the breezes?
I'm sending the question along to Dale at Chiff and Fipple too, in case that's where I saw the answer...
