Hey Doc Word.......I tried a "Bird" for awhile, but somehow the damn thing is always in my road and bothering me. I still rely on Shubb, but if I'm just screwing around I use the Kysers. This brings up a couple of other points though..........
If the capo you're using bothers you, try something else. I don't know what it is about the "Bird of Paradise" that gets me, but I just can't stand it, even though it works better than the Kysers.
Also, read Rick's post above regarding slitting the rubbers on the capo. A properly cut Shubb is about unbeatable,especially on a 12. But you can improve any decent capo with a little work.
