What I've seen so far with the jibs is that the shape of the full batten one sucks in light air. The top of sail turns flat as a board. Another team has had some luck cramming the battens in to keep shape in the light stuff. The roller furling jib is definitely easier to get a nice shape in the light stuff. When the wind picks up I like the shape the full batten sail gets up top, but in reality I don't think it's that much different from the roller sail. At this point I think I prefer the roller sail. We haven't rigged our self tacker yet, I didn't realize we'd need a new jib...
