Thanks for that Bear. It looks interesting. The angle would change the normal thumb pick attack. I can get them from international suppliers online. I need to work out the right size for me and whether anyone stocks it.Shel- you don't have the good ones! The best I've found is a Zookie by Jim Dunlop. The reason they are best is because the tip is at an angle to your thumb meaning your attack is square to the string. I use 20 degree.
Here's a link:
If you can't find them PM me your address and I'll send you a couple.
