If I'm going to be away from the boat for a while, I tie a sail tie around the furled jib, after wrapping the sheets at least twice around the furl.
Guess I'm being a belt-and-suspenders guy.

Joe I think that it is a great idea, I do this every time I put the boat to bed. This is because if it does get really windy, I usually don't sail my CD.
I have been using the same Harken roller furling/reefing system for over 25 years with no problems. I have a 147 that was cut for me 3 years ago [with a foam luff] and older 150, [circa 1985], and a 100 I had converted from hank on to a grooved luff for the furler.
I always us the 147; it is just too convenient.
As far as Furling sails tearing, and furler failure; I think this has more to do with maintenance.
Replace your furler line at the first sign of wear.
Keep up your maintenance of the sacrificial foot and leech. Once UV breaks down the strength, it will tear; even rolled up.
As Joe says Roll it tight and put an extra sail tie on it.
Lubricate the bearings regularly, and keep the groove clean and lubricated.
Now for you aesthetics guys. You make a good point. Hank on’s do look pretty.
As far as the argument that you get a better sail shape with a hank on. I'm not buying it. You get a lot of turbulence if your leading edge is a wire, some un-aerodynamic hanks and a space in front of your luff. Most Roller Furling systems have a nice clean leading edge.
AND while your point about sailing a partially furled sail is correct... we are talking about a boat with a hull speed in the single digits. I suspect you could get more speed by keeping your hull clean, or reducing weight aloft.
