Hi there senor
You will laugh, when I did that trip in Scotland ,I borrowed the red dry bag just to have some spare space and to avoid putting heavier stuff in those thin rear panniers, so with all rough riding, they wouldn't get a hole worn in them.
The first day, the bottom of the dry bag came apart, so I had to improvise with a plastic bag to close the end so in the regular Scottish rain, it wouldn't get wet inside.
A frame bag would have been best to put the heavier stuff in like my pump, repair stuff, stove etc
I still like the idea of having a dry bag for overflow food shopping, weighs very little and with voile straps, easy to securely put on top of each.
It all worked out, and the setup was fine on a lot of rough single and double track. The panniers work well, but better to just have softer stuff like clothes, rain gear.
thats a good idea having an extra dry bag, never thought about it. I carry one of these ridiculous thin back packs in case i have to carry food for some hours.
