That's an idea too. Seems, at the factory, they do put a small dab of white grease on the egg shaped cam inside the leg. It is just not enough to really shed water though. Problem is the cam pushes out things that are like mini brake pads. If you get grease on them, and the inside wall of the leg that they press against, then they won't grab.
Plus the whole thing is a real pain to take apart. it is not designed for disassembly.
Trigger sticks do work well, fast to deploy, and work for me standing at 6 ft 2 in. You just have to keep them from getting too wet. I don't use mine in rainy weather anymore. Drop one in a creek and your screwed.
All good points re taking the legs apart and grease affecting the internal holding power of the cams. I'm thinking about a Bog_Pod RLD-3, and just concealing the red on the legs. Many good things said about it in reviews. I already own one of the medium sized rear scissor type supports, but what used for a rear support can change with every shot. I prefer not to tote extraneous gear.
