Well... between the two, I think you know already which one I'd choose, Illinoisbow.
In fact, I had a lengthy phone conversation just yesterday with the gentleman who runs Whitetail.com about this very same thing.
ASAT is great, don't get me wrong... but I still don't care for it's monotone background.Yes, its striping tends to confuse the eye (I've heard several people make the statement "deer just don't know what to think when they see this stuff"), but I'd take the sheer contrast principle that Fall Gray relies on any day. It still utlitzes some "sticks and limbs" on top of that, but that's just icing on the cake.
You may or may not have seen the thread I posted a couple days ago in here; I think it was titled "An interesting camo comparison..." or something like that. I can't remember if you responded on that thread or not... Anyway, if you haven't seen it, it's probably on page 2 by now. Do yourself a favor and look at those pics on that thread again. Also, read my commentary on there as well when I was explaining to a couple readers my intent on posting that...
One thing to keep in mind (and you probably are, or you wouldn't have already narrowed your choices down to these two great patterns), is that for 99% of bowhunters, how they will be seen by deer is
from the ground as it looks
up into a tree. For this reason, I prefer Fall Gray.
Take a look at this pic below, and you'll see exactly what I mean:
I honestly don't think ASAT could hide that hunter anywhere close to as well as that guy. Look closely, he's right out in the open, and not partially hidden behind a myriad of trunks and branches. The fact that he as a hunter is basically skylighted makes my point even more. I know we as hunters try to use the trunk of a tree to break up our outline, but how many times has a deer come in from an unexpected direction? It's been my experience that being sklylighted is my number-one concern while being in a tree (after stand selection, wind direction and all those other criteria are factored in before I even get up in the tree).
If you've got a tangle of big limbs or several twisting trunksbehind you to break up your outline even more, well... this pattern is just going to be
that much more effective and harder to spot from the ground.
Finally, I know there's some serious ASAT supporters in here... and hopefully you'll see I wasn't trying to slam the pattern. If I couldn't find Fall Gray on the market, I would give it some serious consideration. I think when this new Enigma pattern gets tweaked a bit in terms of contrasting background, it will be
very much worth looking into. Just right now... I don't think there's anything close to this pattern in terms of the contrast and ability to just plain obliterate the human outline. Not even close. That picture speaks a thousand words.
