Ok, I’m on a quest for the absolutely most mellow sounding soprano D whistle on earth - high-end, low-end doesn’t matter.
I currently have the following soprano D whistles: Clarke Original, Clarke Meg, Clarke Sweetone, Susato Dublin VS, Susato Dublin S, Susato Kildaire V, Feadog, Little black whistle, Waltons D, Waltons Mellow D, Acorn, Oak, Water Weasel, and a Generation. Of these I find the Clarke Original to be the most mellow.
Thoughts - recommendations?
Low-end I find Oaks to be pretty mellow.
Medium-end (price-wise) Hoovers are wonderful.
High end: Burke. Definitely Burke.

A clarke can be pretty darn mellow. Can be.
No one mentioned a meg?
Dare I say . . . the Walton’s Mello D? Very aptly named.
I agree the Clarke original is pretty mellow. Oddly, although it I think it sounds very similar to a louder Clarke, I don’t think the Serpent Sweet Polly is “mellow” - more “husky” and “warm”
I think the Sweetone is slightly mellow. Some (but not all) of my self-tweaked Generations are mellow.
Not a D whistle, but I think the Walton’s C (same head as the Mello D) is even more mellow.
That is quite a list of whistles you have there.
We would like to know what you mean by mellow. What qualities would you include to consider a whistle “mellow”?
If it evokes thoughts of a clarinet.
Hoover.
Hoover.
Hoover.
No, no. Hoover. (Oh, is that what you said?)
Can you repeat the question?
My mellowist ( is that a proper word Bloomfield?) is a gen nickle d I murdered whilst tweaking then restored thanks to advice from vomitbunny and others.
Since it’s a two syllable word, it can take the “er/ist” ending or it can be used as “more/most mellow”. I’d use the latter.
P.S. I’m sorry I’m not Bloomfield.
Thanks and no need to apoligize, I respect all folks what have book learnin 
Ha! I have very little, though (but I’m working on it).
Hoover.
The most mellow of all whistles would arguably be either the Charke or the Shaw. Unfortunately the Shaw is almost unplayable in the second octave due the high air requirement, and any tweaking to make it more playable might compromise its mellowness.
Might want to try a Dixon out.
Thoughts of a clarinet are the kind of thing that might make me throw a whistle away violently.
The Humphrey wide bore is mellow, maybe?
Out of my small collection of high d whisles, my Clarke is the most mellow, followed by the Oak if played quietly. My Walton’s Little Black D can also be played quietly, and sounds sweet when so played.
How about an Alba Q1, or Alba Parlor Whistle? They were designed for quiet playing, and if they have a breathy sound(never had the chance to try an Alba) like Albas are said to, then they might be worth investigating. Big Whistle shows both.
Except that it’s “er/est” and the word is “mellowest”.
P.S. I’m sorry I’m not Bloomfield.
Oh, no, you’re not. 
As in a very complex voice in just the right combination to not sound too airy, or buzzy or anything else.
Hmmmm, thinking. (and no razzing about that either)
Ok, I dun thunk about it. I would have to say the most mellow one I have right now is my Lon Dubh (which is for sale, btw). No harshness there.
Granted.
P.S. I’m sorry I’m not Bloomfield.
Oh, no, you’re not. >
I’ll take your word.
