We did the Crater Lake Century and it was cold when we started out, so I wanted more room to stash clothing, food and my full-sized camera. I had PLENTY of room and could easily have carried more! I loved it. Big thumbs up from me (and I also ride a small frame without much seatpost showing)....

That is my jacket tucked under the bungie cord on top. I do have a non-carbon seat post, by the way.
The picture helps a lot, thanks! You certainly do not have more seat-post showing than I do. This is looking more and more like it will fit my needs, am waiting to see what feedback I get on the rack vs seat-post bag thread.
