Ever hear of Murphy's law? Just didn't want to take a chance on that tab snapping off when I'm at full draw on my next book buck. Probably would never, ever happen -- especially if the rest was set up exactly correct so that the draw strokepulled the string justenough to lift the arms into place and didn't keep pulling hard on it after that...

Cougars, I honestly don't know... but I'm guessing somewhere around $70-80.
