Anyone here have a Gorillapod Focus or Gorillapod SLR? I'm specifically looking at opinions on these two models since my camera gear will weigh approximately 2.5Kg. I want to know if anyone has either of these two and have loaded them up to somewhere near the weight limit. I have seen these all over the place. They look cool, and I even had a tiny one for a really tiny camera. Do these handle the weight? Do they get loose over time and fail? $160 is a lot of money for something which I have always considered a toy. Any experiences? Would you mount your camera on a tree above a river using one?
