Amen on the OK wind. I've used the ScentLok Savahna suit forthe past three years and have had good luck with it. It reduces sent but does not eliminate (and nothing will, that's just marketing B.S.). You still have to pay very close attention to scent control.

Opening day I had a young 7pt bed down for 2 hours down wind of me 8 yards away. My stands are only 8-12 ft off the ground. Have I been busted? Yes, but not as often as I used to get busted.
