I have the 56 L World Tour panniers and I LOVE them. I've used them for a couple of tours last summer + grocery shopping during the year. They have been the most durable and cleverly designed panniers at that price range.

Also, to add weight to what Velonomad said. I bought a pair of Vaude panniers and within one tour (a short weekend tour) they broke!! So, all I can say is STAY AWAY from Vaude.
