Hi, I’ve been playing for many years and so when I joined up here recently I worked my way up through your beginners section fairly quickly, but then on the start of the intermediate section you begin harping on crossovers and practicing all your exercises both by starting with downstrokes, and then with upstrokes; I believe you when you say there is a difference. Maybe I might have missed it when I started studying how I play because I started alternate picking so long ago.
In short: Does practicing starting with upstrokes ever come back around as a necessary small finesse type thing that helps with higher techniques such as economy picking, or sweeps?
