I think I'm still exploring several options here just recently tried to turn my wrist after watching MAB videos seems to help get a bit faster but before that I mostly practiced with a more vertical approach, I try to demonstrate both here. I have issues getting faster than what's on the video (even though I made good progress recently) cross picking seems very hard to do I think maybe I'm wasting too much time on upward motion. I did not include any sweeping here but that's something that's not too hard for me , tremolo is on another hand much more difficult so it seems I have more problems with the classic alternate picking technique and cross picking. Thank you
