To chime in here, the difference in using the parrel beads (or an ATN tacker) and not using one, might depend on what type of angles you are planning on sailing. If you are using the asym for broad reaching, then the parrel beads will be some benefit with the luff tightened down a bit. OTOH, if you plan to sail deeper angles off the wind you are better off without the parrel beads, allowing the sail to float out away from the headstay and out forward of the boat with a relatively loose, curved luff.

Any way you do it, those sails are a lot of fun & can really give your boat a fun kick in the rear....like a turbocharger!
