Many times words don' t come out sounding the way they are meant, and I' m sure this is the case here, but I do take exception to your implication that anyone shooting a rig like your Caribou is NOT after a quick, humane kill. That' s an insult to every traditional shooter or short draw archer that' s not able to get a heap of steam into an arrow.

But enough of that.

For a backup bow, I wouldn' t get too far away from your main bow. Different grips and different format designs don' t shoot quite the same and you won' t be spending as much time shooting the backup as you do your main bow. So, keeping both bows as close as possible in design and setup so you are familiar with both their shooting qualities is very important, IMO.

I' m a tightwad, and I don' t like spending a whopping amount of cash for a bow I don' t intend to shoot very often. If I were to get a backup bow, grip style similar to an UltraTec and keep some kind of consistency to what you' re used to, I' d look hard at the Reflex Gamegetter. 39" axle to axle, 7" brace and you can get one for a shade over $200. It doesn' t have all the bells and whistles of the UltraTec or any of the other high end bows, but it is plenty bow to save a hunt in a pinch.
