I use the Panniers of Hepco & Becker. There Panniers made from Aluminium and Plastic are a perfect compromise between durability and weight. The both 40/37 ltr. panniers are more the big
enough for all your stuff and loadable up to 10 kg.

The crash bars are also from Hepco & becker Made in Germany. Available in two colors (silver and black).
