I started using the predator fall grey and the Asat leafy suit last year and I did notice a difference in the deers reactions when they caught me moving a couple of times. When I stopped moving they immediatly went back to feeding. In the past they would stare me down for several minutes before the went back to doing what they were doing or even get nervous and walk off. I also killed 3 times as many deer last year as had in previous years. I'll never go back to standard camo.
