Anyway, I remember seeing a video of Paddy Moloney playing a whistle with what appeared to be black electrical tape on the tube where his thumb(s) go. So, I did that with all the nickel tubes, and put a small square of it where my pinky rests. Big improvement!!!! Now, once the pinky is out of B3's way, and the thumbs aren't sliding, the grip is much more relaxed, and the fingers are more easily doing what I want them to do. Even the more up-tempo tunes can be played on the Bb now.

Other types of tape and materials were found doing a search of the forum, but I thought this would be another easy to find option for anyone who likes nickel whistles but doesn't like 'em slipping around.
