This stick, stake, rock, trekking pole method illustrated by Steven can also be used for the BA Fly Creek UL 1. I have a Fly Creek UL 1, and I sometimes prefer it, especially when I'm going to be in super buggy areas. It's as light as most tarp/bivy combinations, and it's super quick and easy to put up. Every place I've packed (and kayaked) has had some kind of rocks, sticks, etc. If there are no sticks available, a long, narrow rock can be used as the object to be weighed down by two heavy rocks. Without carrying all of those stakes, it's very light (and compact). It can also be used as a tarp shelter only, which (if you don't carry all those stakes) makes it an incredibly light shelter.
