Hi Emil! Thank you so much for the reply. Here is some tab that perhaps better describes my question. This is how I learned three note single string runs. My guess is that you play these kinds of runs with alternate thumb-index, no matter if the last note is an upstroke (Index) and the next note (bottom string) is a down stroke . I am working on using your slide technique but I am also trying this in a new-to-me way. Have a great day.
