Hey Bob, this is an interesting thread, lots of philosophy pouring out of stories/experinece in bending or breaking rules.
Having been diving since '78 I've busted a few rules as well - mostly the solo thing because of photography - nobody wants to go that slow! However, in recreational diving (non-tech), I'm of the firm opinion that most dives go well (either following the rules or breaking them) not because everything was planned and executed so well, but because nothing went wrong. Most don't practice emergency procedures often enough, if at all, and most are not wearing/taking the appropriate back-up gear to deal with the more potentially serious situations that can arise.
For me, at the end of the day, when diving on my own (or with friends) I'll bend what I feel can be (like no dive flag), but when on a charter or at a place in the tropics - when in Rome...
