I'll be doing some airline travelling soon and I'm hoping to avoid checking bags. The trips will be both for business and pleasure, so I can't carry my current messenger bag with my photo gear (it's too small to fit a laptop + camera). I'm thinking about picking up something like a Timbuk2 hidden messenger to use with an insert. For the flight I'd pack the insert in my carry on along with the folded messenger. This gives me the option of using the messenger as extra space on the return flight while staying under the 2 bag carryon limit. So far most of the inserts seem to be much larger than I really need. I have an Olympus E-PL2 with the kit lens, kit zoom, and the pancake lens, my entire kit will just about fit in the same space as a dSLR w/ kit lens. I've been looking at the Camaroo Compact II or the Mountainsmith Kit Cube. The main issue is...they both seem a bit bigger than what I need. Does anybody have either one of these? How well does it work for m4/3 gear? Any other recommendations for inserts sized to fit smaller m4/3 gear?
