Hello, and welcome again !!!
I always liked the way Yngwie plays arps along the neck (inversions) but I thought it was much movement to just one arp and it was restricted to 5 positions (at the best) depending on the zone of the neck. I found one easy way to do it (at least for me!...). It goes in a vertical direction as opposite to Yngwie´s one (more horizontally).
