Working on my 902 picking with this a bit, I’ve been working on this section for the past few days.
When practicing this, I’m trying a few different picking styles and alternating. The big thing I’m trying to do though is force myself to strictly alternate pick - adding string skipping seems like an alright obstacle to economy picking the lines.
What I’ve been doing is practicing each 5 note chunk, starting on a downstroke on the first, upstroke on the second etc, and giving a little space between each chunk, then working on reducing the space between the chunks. Another layer to that is I’ll start combining chunks into ten note chunks and letting them be some space between those bigger chunks, working through the piece pairwise. And also just work through the whole thing smoothly and slowly without full speed chunks.
