I use MAx-4 for everything wether im in the swamp botoms or the grass lands. I was leary the first time in the bottoms cuss when I use to use a shaow grass as my blind and camo I would have alot flair as the where coming down. But max 4 I have had great results. Not my camo, boat blind and dog vest is max 4. If im in a true marsh I put grass matss up
