I think the small-shackle is over-rated. I think a better option would be a long, narrow shackle, like on my On-Guard Mini... when I lock, it goes around the wheel and frame, and then around ye aulde stationary object. Long enough to encompass all of that stuff, but narrow enough where there's no use in breaking out the bottle-jack. (I also mix it up with a padlock that has a flexible armored-cable shackle.)
