They don't look much different to the Oxford 'sports' panniers I bought years ago. I've used these on the Ten with no problems. Bit of a faff to get em on but nothing difficult. I put everything in bags to keep dry.

Only trouble with this stuff is if you expand them and pack loads of gear in, they tend to hang inwards under their own weight, but I can pack in enough for a wkends camping no problems.

If you want to carry loads of gear then probly better off with some panniers/cases, though I just hate the look too LWR for me (though tempted by those ARD cases), for travelling light and �30 sounds good.
