Lessee. I own (in alphabetical order) Abell, Bleazey, Boisvert/Greenwood, Busman, Grinter, Schultz/Thin Weasel, Swayne, Syn, and Wilson. I have owned Rose and Sweet, and had an O’Riordan C/D set on loan for awhile.
It would be impossible to pick a “best” among them. First, I will say, the Rose and O’Riordan are way too pure and sweet for me, and I like whistles that lean toward pure and sweet. The Sweet, and old-style, is too unbalanced, although when I gave it a few toots before I sold it, I thought I had judged it too harshly. Really not a bad whistle, especially for the price.
Abell (blackwood): very easy to play, quick response, sound is a tad on the breathy side, but bright other than that.
Bleazey (boxwood): All-wood, tapered bore, MUST be played hard. Loud in the upper octave, but the boxwood and all-wood design really make it so that it’s not a screamer.
Boisvert (boxwood): The mellowest-sounding, some might say woodiest, whistle I own. I think, if all his whistles are of a similar design, he should make them all out of boxwood. This is a heavy-walled instrument, and the tuning is very sensitive to breath pressure.
Busman (bocote): Very easy whistle to play, although it has more backpressure than the Abell. Mellow sound, extremely well balanced across the octaves. Good for both airs and dance tunes. Very versatile. One of the prettiest whistles I’ve ever seen.
Grinter (cocobolo): all-wood design, narrow-bore. Sound is sweet and moderately chiffy, lightning-fast response. Well-balanced, doesn’t scream in the upper octave. Another extremely beautiful whistle. (BTW, the low-F is a great instrument, but the low-G is even better.)
Schultz (cocobolo): Sound is sweet with a little chiff. Can be played gently, but really thrives on being played hard. Loud, but well-balanced. I have three other Thin Weasels (E, C, and Bflat), each of which I would say is the best whistle in the world in that key. I love the D, but I’m not gonna say it blows every other D out of the water.
Swayne (boxwood): All-wood, tapered bore. This is a pretty easy blower, has a mellow but sweet sound. Well-balanced across the octaves. It doesn’t really lend itself to one style of playing over another.
Syn (brown lancewood): all-wood. This is rather like the old-style Sweets. To reach the upper part of the second octave, you really have to blow; very unbalanced.
Wilson (blackwood): This was one of the first whistles produced by this guy, who is a fife maker; his shop developed QC problems and stopped making them. It takes a little more air than most woodens, but is still really easy to play. The sound is full, and well-balanced, sound is a little dark and chiffy. Likes to be played hard, but can be pretty mellow, too.
I probably play the Grinter, Schultz, and Wilson the most. I take the Bleazey out when I want a challenge or when I really just want to play with reckless abandon. The Busman and Abell come out when I want to be more laid back, and every time I pick them up, I wonder why I don’t play them more. Same with the Swayne, which I play even less often. I still haven’t mastered the breath-sensitivity of the Boisvert (I will note that this similar to the O’Riordan I played).
The Schultz is far and away my sentimental favorite, while I would say that overall I enjoy playing the Wilson the most.
Oh, and BTW, the whistles aren’t on Grinter’s site. He’s been planning on putting them up since, what was it, 1998? A D is 240 euro last I checked, which was probably early this year.
