Barry,
If I remember correctly, the Nelson-Riggs bag wasn't supposed to sag either. It has a cloth covered piece of cardboard or something that velcro's to the bottom, but the narrow and short sissybar rack makes it droop like an old lady's, er, well it droops....
A guy I work with has an old Suzuki and it has an adjustable sissybar rack with a big black ugly knob on each side that holds the sliding part in place. I don't know if the demand would be enough to make it worth Brent's consideration, but it sure would be nice to have a fix for this..... I may end up doing it myself, one of these days....
