I like the looks of both of those bags! The Topeak model I was looking at doesn't seem to have the clip feature that would accept my Garmin - I knew I should ask the TE'ers for input. Maybe I'll buy all 3, then return 2. I also like the looks of the Ortlieb seat pack too - mine is a bit small for touring. I'll let you know what I end up with! Thanks! tokie
