Have a look at Frank Thomas' cargo range - they are well made and have that magic spiral zip thing that allows the bag to expand if you put a lot in - or shrink if you only carry small loads
I bought the kind of rectangular version for my Bonnie but they do a slanted version for sports bikes
Their Monster tailpack is a good piece of kit too - with some extra bungees it's solid as a rock
Not expensive either
Handy hint - I have a drypack waterproof kit bag - the sort of thing canoeists and sailers use with a roll top seal - I used it to keep all my sleeping gear in (Therma-rest mattress, sleeping bag, inflatable pillow, some spare clothes)
- I use a Macpac Celeste for two up trips and the Hilleburg Acto for solo - its a brilliant tent, quality design and manufacture and weighs only 1.6 kg - keep your tent in a bag (I use rubble sacks) to keep it dry if it's raining while you are travelling and if the outer is wet when you pack up keep your inner tent in a separate rubble sack to keep it dry for the next night
Cargo nets for bikes combined with bungees of various lengths are very useful for holding things securely
In Scotland rain may well be your enemy so for the things that MUST remain dry try double wrapping - put clothes etc in small bin liners and then put your bin liners into a tough sack like a rubble bag before they go into your panniers
Here's a picture of the Cargo panniers and the sailbag on my bike and the Monster tailpack on my (then) girlfriends bike
