Touring Equipment

My post seems to have disappeared in the Merge? Anyway.
I use a Carradice with SQR daily and it's a great way to carry 10 to 20l of stuff. It's really stable, easy to remove, reasonnably waterproof too. I use toe straps to secure a jacket on the 4 externals hooks when required. Seems perfect for your requirements.

I shall harass my LBS to get me one in to try. The reviews on wiggle are mostly positive but with a few mentioning stability issues. I guess its something you have to try. I like the ease of removal idea, i may even throw the associated mounts onto my MTB to use it on that too. I'll report back if i purchase but please keep the ideas coming.
