Well, as long as you're asking! I got on a kick to own cheap tin whistles. I am in no way accomplished. But when I can make acceptable music, here are my perference based on quality of note, going from one octave to another, ease of fingers to cover holes, and lack of overtone. 1. Soodlum mello D (the company is now Walton) is most consistent. It is larger than other whistles. They can fit inside. Definately more MELLO. Some people have commented that this whistle requires too much air. 2. Doolin D (two piece). 3. Walton Black D. 4. Feadog D, 5. Oak D 6. Generation D. I have played a Clark D with the wooden bit briefly but would not rate it above 5. 1 to 4 are brass. I really like to use C whistles, seems that lower sound is more pleasing for airs and easier to shift to higher octaves. I have the Generation C and a Sweetone C (the cheapy nickel) and both seem to be equally good. I have several Generation in other keys, but don't play them that often. I much prefer the bass to the nickel; seems less harsh. Again, this is just an occasional players opinion.
