*o I can't decide to go with the asymmetrical cruising spinaker or their utility power spinaker. I have a 100% jib on a roller furling. Which sail will be easiest to install and use. Which will round out my sailing needs the most. I don't use the jib halyard, since i have the roller furling, can I use that for the spinnaker halyard? I experience light air most of the time. How much trouble would it be to add the harken furler for the utility power spinnaker/UPC and keep the jib furler?
