I love your videos, specifically for the gun cam. You can actually see who you are shooting at, rather than assuming there is a guy over there in the woods somewhere. I couldn't agree with you more that the standard GoPro helmet and gun cams simply don't tell the whole story. Helmet cam plus a zoomed gun cam is by far the best video out there IMO.
I think where you are really getting hammered is that you are using a full size camera. Its big, its heavy, and in comparison, its pricey.
People seem like they are blowing you off, but I bet if the little Greg Hastings camera, or GoPros came out with a zoom lens, we'd start seeing a lot more videos like yours.
