I used scent a-way. None of my buddy's use scent blockers, but I swear by them. I'll check out those wafers tho. Always looking to try new things. I have always been outspoken about scent and wind. Even the one bud of mine would use his wind dust rarely. I'm on mine constantly. Even with the best scent blockers, I maintain that it doesn't take much to ruin a hunt or stalk. Evolution really helped these critters.
