OK, I read through the attached link, and specifically killcrap's method with the triflow. I don't know - that sounds pretty risky. It seems like there's a pretty good chance of breaking something using the method he describes. It's probably OK for someone with a lot of experience with this sort of thing, but for those of us on our first go-around, I think I'll stick to the pick method for now. I just bought a new set of picks, so I'm ready to try again. Wish me luck...
