Terry--I adhere to KISS sailing--I have traded headsails while racing and found that two slots in the foil worked best when changing 2 sails. Sails without reefing luff pads are more efficient, point higher, are easier to hoist, less expensive, and can be bagged much faster.
So, if you are not into high performance sailing, the average single slot roller furler with a 150 genny with reefing luff pad will work. You can sew the pad onto your existing sail for about $6-8.00/ft. Just don't expect to out point a Precourt
I am changing our my CDI FF2 for a Schaeffer CF700 furler with a 104 jib--no luff pad 'cause pointing is more important to me---and if things get too wild, roll up the jib and sail on the main, just like Roger sez in his movie

. If you don't trailer, then any aluminum foiled system will work--Harken, Profurl, etc. Since I intend to road travel long distances this season, I will remove the jib from the furler/forestay while trailering to reduce sail damage at 65 MPH so a quality flexible foil is important.
