Panniers: how big?

[Melalvai]

The main downside of my panniers is I spend a fair bit of time snarling at the hook on the lower bungees. They like to have bungee sex with each other. They like to catch on grocery carts. They like to engage in exotic mating dances with my rack... I have no worries about the panniers falling off the rack tho.

I'm almost afraid to ask what sort of offspring is the result of all this?
