Dennis: I purchased a 300SF Yankee and Furlex furler from Kern - and it works well - I find that while you unfurl the sail- you must drag the furler line so that the coil on the drum is tight. If not when you refurl the sail - the lines will over wrap and jam the drum.
This may be a common issue and not just with Furlex - I don't know.
The Furlex kit included a new forstay and fittings - I did the installation myself - fairly straight forward though the directions could use some tuning.
Below is the Alado furler - I saw two W32s with this style at the 2012 Nor Cal Rondy.
Cool part is that the drum is open, with few part and you can install w/o removing the forestay... pretty interesting and the owners liked the furler.
Good luck with your choices.
