Regarding the dynomighty, I don't think it has any sort of tilting options. If that's the case, you can MYO.
I can't find my link to pictures etc (might have been make magazine), but let me describe how to make one that probably weighs considerably less:
- At your local hardware store, find a 1/4-20 nylon bolt (about one inch long is good, YMMV), a matching nylon wingnut, a matching nylon regular nut, and two start lock washers (not nylon, and in any case, optional)
- Drill a 1/4 inch hole in the center of a bottle cap from whatever size bottle you are most likely to have with you while hiking (2 liter soda, power-ade, whatever).
- Feed the nylon bolt up through the hole from the "inside" of the cap, firmly attaching it to the cap with the regular nylon nut (and keeping it in place with the optional star washers, which I've never used myself)
- Thread the wingnut on UPSIDE DOWN so the wings point down towards the cap. (to tell you the truth, the wingnut could be considered optional as well, especially if you are worried about fractions of an ounce)
To use this, screw the cap onto a bottle (not empty since it needs balast to keep from tipping over). Screw the camera onto the nylon bolt. Tighten the wingnut up against the camera to keep it snug.
Note: most of the weight savings comes from using nylon hardware. The original design used stainless steel.
Note 2: I've created a variation that is tiltable, but haven't tried it in the field yet.
