Rancho safari here as well. Love it, hot, but love it. Wouldnt still-hunt without it. Turkeys seem to be especialy oblivious to it. Stalked to 8 yds on a flock last year and got my first bird with a bow(granted it was the perfect storm of events in some thick stuff). When I started thinking back, I've a had all sorts of close stalks on turkeys with it on. They dont seem to spook out of the county either. Just kinda feed away if they dont like you. Trim the arm, use an arm guard, and wrap a cord over the back of my neck and then under my armpits, around my back and tie on my chest. I think the samurai used to do something similar to free up some range of motion and keep the sleeves up on the arms.
As a bonus, I tie it around my rail(and let it hang down in front of my legs) on my treestand. If a deer picks you up, it is way less likely to spook if you dont move (in my experience).Great for those trees that you know are too visible but are too good to pass up. Guess they think its just a big ugly squirrel in his big ugly nest.
Good Luck
