If you are going to trailer your boat a lot (stepping and unstepping the mast frequently), you might want to consider a flexible furler of which there are two brands which come to mind. CDI (Cruising Design) or the Schaefer Snap Furl. The CDI uses their own halyard system and so you will not need your existing jib halyard. This is by far the least expensive furler out there. It works good, but not very sophisticated. The SnapFurl uses your existing halyard and so if you have more than one, you can use both for headsail changes on the double groove, but most people except racers put it up once and leave it up. If you keep the mast up all year then you might want to consider a furler with an aluminum extrusion, which are usually of better quality and work the best, but obviously are more expensive. The ones that come to mind are Hood, Harken, Schaefer, ProFurl, and Furlex (there are others, of course). These are all decent systems, but I think the best, by far, is the Furlex. Many of these brands sell you the basic furler and then you have to add the block kit for bringing the furling line aft and the halyard restrainer to eliminate halyard wrap for additional money. Furlex includes these in their initial package and also you get a new forestay which assures quality control over all the components. With the others you put a new furler on an old forestay. If you compare prices with the top of the line systems, then I think you will find Furlex quite competitively priced. The one thing you want to do to make your installation go better, is to get the exact pin to pin measurement of your forestay with the mast up and tuned. If you cannot get that while the mast is up, then mark your forestay turnbuckle with tape so you know where the exact location of adjustment is so you can recreate that measurement which you will need before you start the assembly of any system.
