I've killed quite a few deer w/ scent lok, and quite a few w/o scent lok. Doesn't matter, we (humans) have a scent all of own own. The second we step into their living room we leave a sign. Synthetic fiber has a scent all its own that is foreign in the woods, as does dye. Use it and use the wind, that way you did all you could do and sleep well. I'm big on using the wind, no movement, no noise and sit for long periods. Usually the deer you see, were about a mile or two away and had no idea you came in.
If that helps ya.
