I just picked up this old furler unit for not much money. I am looking for an inexpensive way to make my life easier. I contacted Schaefer, and they sent me the instructions for their current version of the free flying furler, however, this unit seems different. According to my local rigger, these units are used in conjunction with the head stay, and do not replace it. I understand that it's probably not the most efficient system, but I think it will work quite well for me. Does anyone have one of these? According to Schaefer, they haven't made them in 15-20 years. Any thoughts?
