the only thing I could see being a factor is just making sure they wouldnt jump off hitting a bump and doing any damage to the rear derailleur or anything, with the hard edges.

Thank you! Definitely yes. I bought some real rack mounts with rack locks, they're designed for DIYers. I followed someone else's plans for the bucket panniers. They were pretty stable and weren't going anywhere. But I think next tour I will make bags with those mounts and not the buckets. Just because I will be carrying less (learned what I really need and what I don't need) and the buckets would be too big. I will miss the fact that the buckets made a very flat surface across the back though
cheers!
