I'm trying to remember who was it who suggests that in their tricks..jonez, maybe? I just saw it today.

A large part of sweeping is figuring out what works for you becuase it's a difficult thing to really describe parts of it. That's why I know this post probably isn't going to help much.

The main thing with sweeping is don't tear your finger off the fretboard after you hit a note. Keep your fingers relaxed and close to the strings and start slower than you think you should.
