Whatever luggage you will be using, if any of it requires bungee straps then I can very, very heartily recommend Rok Straps.
Part bungee material, part webbing, they are like an adjustable length bungee strap.
Thus you can set both the length AND the tension accurately for each different situation.
I bought a pair at the NEC show years ago and they have rendered all my previous bungees completely redundant.
I even had a (miniature) dishwasher strapped (in total security) on the monster the other week.
Not cheap, but definitely recommended.

Also it might be worth checking your local Aldi.
Last year I bought a large, waterproof, roll-top stuff bag from there, really cheap.
Perfect for a load of camping gear etc.
They may have them again this year.
