My vote goes to the Acorn, followed closely by an untweaked Generation.
Oh Blooooooommmmfield!!!

I’d vote for the Cooperman (?) found in US historic sites throughout the nation. You know, the plain, tin Clarke like whistle.

I have an untweaked Gen that sits in my back pocket for just such a reason.
I gave away my Dixon tuneable (not the brass slide model) because we didn’t have any subways in Salinas.
It was way out of tune with itself. However, it must have just been a fluke, because I’ve since heard one that sounded excellent, and several Chiffers like them a lot.
If I couldn’t have gotten Whitecaps for them, the same would have happened to my Feadog and Oak. In those, it was the ugly, raspy squawks that would have done it.
Either an Alba or Overton…LOL, just kidding of course, hey its a Monday. Actually I would probably leave a Generation just because even with them Tweaked they just don’t carry the sound I care for.
have the pakistanis gotten into making whistles yet?
Otherwise, Meg, and Cooperman.
Clarke original and Feadog…utter beasts 
I take it these are all whistles you’d rather NOT have 
Feadog has been on my list as ‘whistles I want to get’ and unfortunately Acorn is one I have. It can be a pain in the neck to play sometimes because they are so sensitive – I can go into the upper octave without much effort.
Someone leave all those oaks and gens and such where I can find them.
They just need a little work.
Hehehe.
Yes, dear? 
Shaw Low D. I owned one for a couple of hours once.
Walton’s Mellow D. The one I have is atrocious.
So was mine, I think I got a bad whistle 
I did try a friend’s and it sounded great so I might try getting one again in the future.
I think that boat has sailed for me. I might give the little black D a try if I ever run across one, but I don’t see buying another mellow D.
