Thanks! Well both feel good in general.
USX I sometimes have the impression I may be adding some forearm rotation to the string transitions and is not just the wrist but feels better than the DSX.
DSX, yes it feels quite different from my original DSX as the thumb is not in contact with the lower strings in an attempt to do it more neutral so it helps in a future switching between both for DBX. This lack of contact of my thumb is also causing for some of the strokes to be way to shallow to the point I think I may be missing the string completely.
I must say I may be one of those persons who has always been used to play with way too much tension so this more relax picking makes me feel/think I have not positive contact between the pick and the string for each stroke.
