LOUD whistle needed. Recommendations?

[MTGuru]

Well, a Copeland high D (brass or nickel) will do for orchestral work. A few years ago, the San Diego Symphony performed John Corigliano's Pied Piper Fantasy suite for flute, where the 7th movement calls for whistle instead. A friend of mine contributed her Copeland D, and reports are that it worked admirably unamplified to fill Symphony Hall. Of course, the fact that the score calls for playing mostly into the 3rd octave up to high-high g' helps.

I'm sure that Sir James Galway, for whom the Fantasy was written, would have used his favored Abell. He'll be peforming the piece again in March with the Detroit Symphony. Hopefully, with a better conductor than this guy:

Added input...

I once tried-out a Copeland brass Low G.
The office workers at City Hall, a mile distant, couldn't understand why their hackles were going up. Invasion of the banshees? LOUD!
I also once had some Susato higher-pitched whistles. Like the Copeland, they were VERY loud! And yes...clear.
