I find the Herco combination thumb/flat pick too light, even the so-called "heavy" ones. Doesn't clamp onto the thumb firmly enough. I also agree about the plastic used in the Alaska picks. Wish they'd improve it. I had to give up on 'em, although the idea seems like a splendid one. So, I just hang in there with a National large on the thumb and real-life nails on the fingers. When I split a fingernail, I use Krazy Glue and Kleenex to build a strong backing. It looks diseased, but it works for me.
