I am thinking about getting a gopro and was wondering if the hero 2 is worth the extra money over the hero? What are the diferences? What are good places to mount it? I am not a big fan of the helmet. Anyone use the chest mount and does it work good? I was also thinking about mounting it to the hood but I think it might not work so good if the skis are off the ground a lot. Any advice would be greatly appreciated. Thanks in advance.
