This is the elephant in the room.

If you want a lightweight folder (and if weight is enough of an issue for you as it is for me), then you may want to take the little bit of time it takes to master symmetrical movements and movements that are not yaw-free (i.e., which order to apply the movements). I'll wager I'm just about as fast with my base tilt, symmetrical movement 1.6 kilo woodie as most are with more sophisticated rigs. It's just a matter of practice (although doing close up and macro work is a PITA unless you have a camera with both front and rear focus).
Don't get me wrong, I love monorails with fancy movements for studio and indoor architectural work, but in the field, after 10 hours of hiking with your gear over slickrock, through cliffs and canyons, etc. I'm really happy to have a compact and lightweight camera on my back.
