Also, it helps to wear properly fitted jerseys so that any little bit of weight in the pockets doesn't result in a jersey pulling on your neck or having your pockets flop around.
The thing I like about a saddle bag, is all my cycling crap (multi-tool, tire levers, patches, spare tube, couple of asswipes in foil packs for hand-cleaning, etc.) are all in there, all the time, so even when I had 2 bikes and would have to switch the bag between bikes, it wasn't a bad trade-off- a few seconds of inconvenience, but knowing that I had all my stuff and didn't have to worry about forgetting anything. (Except for that time I forgot to take the bag!)
