Pick 'em
Although I've got a CDI roller-furler, I think you'll do well with any major brand you pick. The CDI is certainly cost-effective (I say that even though mine was already installed when I purchased the boat), but so are some others. Investigate how each system operates - how easy it is to maintain, how "simple" it is so that there is less opportunitiy for failures, and how easy/difficult it will be to unfoul any failures when you can least afford to do it (high winds, heavy seas, screaming crew). The CDI is a simple system, with little to go wrong; however, it is relatively "light weight", and you'll need to take special care with it when the mast is down so that you don't get permanent kinks in the extrusion. The line can foul on the drum fairly easily, but fixing it is not difficult, even in high wind/seas and a 155% genoa.Given the major brands to choose from, "pick 'em".Michael O'
