QUOTE=slcbob;11439930]I'm stunned at the patience of the audience in again answering another one of these inquiries. Some good inputs.

I'm thinking that's because no one has yet found the "perfect" system for their personal application. I know my pannier is a compromise.

Chaadster had a good list.
I would also like to see some adjustability in mounts. I run the same pannier on numerous bikes and rack types and have had to make modifications to allow this.

Normal things I carry daily
Big wad of keys
big old Cell phone in big case
All my pocket stuff, change knife, lighter etc.
checkbook
newspaper - yeah, I'm a Luddite who still reads print!
The underwear, tee shirt, socks for the day
maybe some food.
rain pants usually stay in the pannier, jacket brought as needed

Things that change day to day
Jeans for the week - usually once a week
Food as needed to stock up my drawer this time of year maybe a couple of ears of corn too
Fridays jeans and sometimes other stuff have to come home

Needs also change season to season.
Spring fall It can go from 40F to 80 over the day
I need to carry clothes I wore in, back home again
Cooler times also require more daily clothes - Tee shirt becomes long sleeve, flannel and sweaters get added


Then there are errand stops on the way home which can add stuff
Not to mention unplanned pickups. - examples are finding a ½" Milwaukee drill in the road
Last week I stopped and filled what ever room I had left with walnuts/acorns that are currently falling
(Johnny appleseed thing - prepping for the inevitable "Emerald ash borer" in my woods)

It's noy unusual for my pannier to weight 10-12#
