I may have just fixed my saddlebag problem - they kept slipping back on the rails.
I bought the express leather saddlebags over the winter, and while they looked great on the bike, after every ride they'd have slipped all the way back and just looked sad.
Plan A was some kind of hook. Plan B was zip ties. Plan C was some kind of little hose clamp, but my worry was that the metal might damage the paint. Then I lucked out - they make insulated cable clamps that have rubber on the interior of the clamp. Bought four of them (5/8") and some hardware to secure them. Looks almost like the clamps belong there - and that's if you're looking for them.
I haven't taken her for a ride to test their effectiveness yet, but there's not enough clearance between the clamps and the fender for the leather to slip through, and the clamps sure aren't going anywhere anytime soon.
Oh, also oil change on friday. 20w50 Lucas synthetic. The old oil was good and dirty (as was expected) with minimal metal shavings (which was unexpected.) She took the whole two quarts. No leaks, and no problems!
