Tail/Rack bag for GSA?

[alfio]

Hello,
I would like to buy a medium size tail bag for everyday use (instead of a top case) that would be fast to attach and detach from the rack may be leaving snap on cords. Do you guys have any suggestion?
Thanks!

I have a Marsee 20L or 22L (I cant remember which) that seems to work pretty well. I got it soon after I got the bike (18months ago). It has stood up well. It usually mounts with 4 snap clips (standard ones you see like on a backpack). On and off pretty easily once you size the straps. I think Marsee has a few updated ones but I have been very impressed with this bag and another tankbag from another bike that stood up really well.

Recently however I dropped the bike in the mud (twice) and with the full bag coupled with some rough edges on the GSA rack it broke and ripped two of the straps off. Not one to throw away a perfectly good bag, I adjusted the way I mount it to a more permanent solution. Using $6 worth of fastners from Home Depot I essentially screwed it to the back rack. I figure this way I will get another couple years out of it.
