Agreed..I don't like the looks of the sadlde bags on a Dyna....I have resorted to a small back pack for items...of course the drawback is the weight on your back and the 'Geek" look...I have been pondering the solo leather bag that mounts on the swing arm.

 

There's another thread going on right now for tank bags and lots of suggestions in there.

I use a Nelson Rigg tank/fender bag for larger items. They make smaller ones too.

I also use bungee straps (from www.bungeebitchstrap.com) for a jacket and strap it to the bars. They are cheap and work great.

 

Sorry, it's not a Fat Bob, but I put a Motherwell's fender rack on my FXDL a few years ago and it really comes in handy. Can bungee stuff direcly to it or throw a bag on.
