I have tried BogPod, Vanguard, and Sniper Styx. They all work. I'm sure the homemade wood/nail/paint/wingnut works too.
What makes it to the stand?
Usually the BogPod if I'm not going far (WAAAAAAAYYY steady, but mine's a tripod and heavy). When I go "way in" I take the Vanguard. I'd use the Sniper Styx, but my son claimed them.
