Picking Exercise

So I am trying to tackle the monumental ( for me anyway) task of learning J.P. Cormier's guitar arrangement of 'Dixie Breakdown' on "Primary Color" which is very similar Mark O'Connor's version on "Markology". The song is a pretty up tempo banjo piece by Don Reno.There is a passage that uses a picking pattern on three strings that is difficult to get up to speed. In addition to isolating the passage I also wrote a little guitar lick that uses the  picking pattern as a starting point and then moves through some triads using the same picking pattern.
