I just received my first BP/W and am in the process of threading it. I initially tried it with the straps straight, with the help of the tutorial on DIR-diver.com. However, it seems like my shoulders are too thin, as the straps are rubbing uncomfortably on my arm even when trying it on. I would like to try crossing the straps, but I can't find a photo showing how to do this. If someone could post a photo of their rig, or a clear explanation, it would be greatly appreciated.
