I recently purchased a K6 DL650 and I am planning on adding a set of 20 mm ammo cans as panniers. I will probably buy the SW-Motech or the Happy trails racks for mounting. From what I have read the Happy trails racks are more robust so I am leaning towards buying them due to the weight of the cans. The SW-Motech have the quick release feature which I am not sure I would use that much. Does anyone have any experience with the two different racks and ammo cans? Thanks for any input.
