Sorry about the strike-through but couldn't get it to turn off. I was particularly referring to top down furlers. I have never had a problem with the code 0 -so it's not the furlers fault.
I sail a lot on my own and have never had a forestay furler. I agree that hanks are safe and easy. We also have a reefing blade and a reefing jib which gives heaps of easy change options.
