I answered 1 - that's what I do when I anchor. And it used to be how I played all the time...
But my style had to change when I broke my right arm (just below shoulder) in Feb 2007 - I was able to play electrics, just, after relearning where the strings were, even during the first 2-3 weeks (it hurt though!!). But because of the loss of arm rotation, I could not lay the side of my hand on the bridge anymore. So for a couple of months I had to learn to play without any damping at all with the right hand - very frustrating, but suddenly a whole new world opened up for me (started to sound more like Hank Marvin and Ritchie Blackmore).
After a few months I was able to put the old hand back where it belongs. I've since lost some of the "unanchored" technique, but it has changed me forever - my playing is generally more versatile and fluent. I think I also have a little of the pinkie resting on the body technique as well now - I never catch myself doing it, but after playing a while, the side of my finger feels like it's been brushing against something, it has that numb "over-stimulated" sort of feeling.
The arm's still not perfect but it's almost there now. I've been picking up my accoustic once every month or so and getting very disappointed with myself. For several months I couldn't get my arm over the body at all, and then when I could, I couldn't reach the bloody strings, let alone put the side of my hand on the thing! Last night was the first time since the accident that I've been able to play it normally with anything like the enjoyment that I've been getting out of electrics.
But I thoroughly recommend trying to play with out anchoring AT ALL for a while it really opens up some possibilities - but you might not manage it without some sort of intervention like I had forcing me to do it - and I wouldn't exactly recommend that bit... (throw yourself down the escalator at a tube station if you want to try it out though :lol:)
