Excellent. Dispels the myth that you can't flake and prep your reserve standing up, just like your main. Folding the excess width, between the A and B lines, up and then on top was a nice touch too. Note that he does a true S-fold by leaving the bottom of the tail on the floor, not bringing it up, and just folds the rest onto it. This is a good technique for new ZP mains to stop the bottom of the tail 'squirting' out from inside the pack as you stuff it into the D-bag.
