We love our Doyle asymmetrical
Ordered directly from the chandlery on this site (SBO), along with the halyard, sheets and ATN sleeve. SBO automatically specs for your model. Very competitive prices and great service. We gibe out front of the headstay, but use the sock all of the time to raise and douse the spinnaker. Well worth the money. Also bought one of the ATN tackers to use over the furled headsail. Also well worth the $. ATN has a great site with videos that show all of this stuff in use. The asymm is our favoite sail.
