yeah @PamPurrs , at my current level, somewhere between beginner and badass, I see two distinct hand positions : the “claw” is very useful to me because it allows a very good control over muting every string when needed, but it closes the hand and reduces drasticaly the amplitude to maybe 2 frets at best. the “flat hand” position, which is the position teached by Josh in the course, allows way more amplitude (both in the horizontal and vertical way) and more control over the notes, but there is no possibility to use the thumb to mute the E string.
I we had to choose/learn only one position, I’m pretty sure the “flat hand” would be a much better choice because it allows an overall better control on everything except muting on the lower strings.
But again my point of view is that it’s always a good thing to have more than one option in our bag assuming we are able to choose the right option in any given situation
Just my point of view at this moment, maybe I’ll change my mind when I’ll be a badass
