About "dragging" your finger in an upward rake, I am self taught and that's how I learned to play. It's good to hear that's it's a "good" and "respected" technique that I see many people using, for a minute I thought I had gone astray. It's certainly better in most cases than trying to alternate going up. Of course going down is a whole nother story, or skipping strings even, those call for alternative plucking finger approach in my style. Anyways, that method can be used either floating thumb or anchored, imo it is the biz-omb!
