Hi all. Looking for my first shooting mat. I searched, but could not find a thread on mats. Any brands to seriously consider or stay away from? I am leaning towards black, but maybe that is not a good idea. Would you suggest a different color or maybe camo so it doesn't always look dirty, or does that not really matter? I have heard people talk about a seam or something at the front of the mat to push your bipod legs against, but I don't really see mats that have this. Thanks for all your helpful advice, in advance!
