Has anyone rated different brands of whistles based on "fingerability?" I've got peripheral neuropathy (annoying, creeping numbness) that's gotten bored with tormenting just my feet and has moved on to my hands. This makes it hard to find the holes in a whistle. Any thoughts on what whistle(s) might be easier to play, and/or any "cheats" for better accuracy in fingering the beasties?
