Hello all. I need help. I am having lower back pains from the vest of my proaim 7000 stabalizer and also seadycam from a freind's vest. We both are new in using the vest. We usualy like doing it with our hands but with the hvx200 and 35mm adapter and all we need the arm. We have a feeling we are waring the vest wrong. I am built like a truck i can bench 300 with out any problems but this gives me lower back pains within 30 seconds of use. i cant find any site that says where or how to ware it on ur body. they just show a person throwing it on. there is also a lower strap and i have no idea where it goes on the body. please all help will be apreciated.
