Thanks for the comments Bees. I used the Advantage Timber outfit last May when I was hunting spring gobblers and actually had a ruffed grouse almost step on my head....

...if that says anything for how effective it was in that situation.
However, I think the Montana River Ghost might work quite well once most of the leaves are off the trees in my area...and I am up in a treestand. I hope to find that out this weekend.
