I always wear "disruptive" dpm, with no probs what so ever. I have used other stuff but other than my guilly suit, no difference what so ever.
The trick is, how you carry youself around your shoot, fieldcraft, proper fieldcraft, takes along time to learn,you cant just read a book and think "i can do that" its time served. but if you cover the basics its a start, and the rest will come in time, as long as you learn on the way.
you can go out and buy the best so called cammo in the world, but unless you know what you are about, it matters not, and would likely be a failed or unsatisfying shoot
