I just bought a RoadMorphG and did a dry run in the comfort of my garage. Using only the tools in my seatbag kit, I dismounted the front tire, took the tube out, re-inserted it, and inflated using the minipump (my trusty Zefal Husky beckoned four feet away ). I even managed to remount my front tire without using the irons.

I found the Morph pump pretty good, and it inflated my mountain slicks to 70 PSI in a few minutes. It wasn't as nice as using a floor pump, but I like being able to pre-inflate the to get its shape correct before inserting it in the tire, etc. I'm willing to make the slight weight trade off.

Best of all, I am now confident I _can_ change a flat in the real world using what I carry. If anything I could probably get away with just carrying one tire iron, but they're small and plastic so I carry two. My kit includes a multi-tool, one tube, one patch kit, the morph, a chunk of old tire to use as a boot if necessary, and two $20 bills folded and taped to the top of the bag (when all else fails).
