RE: bow for wife
Bought a Bowtech LadyHawk for my wife at 40-50 lbs. It is built specifically for short drawlengths, so the performance is better (in theory) than a larger bow that is adjusted down.
It has a 7" + brace height, is under 3 lbs, and the little woman' s score went up 30% in league the first week she shot it. Really well made. Most bows marketed to women are youth bows that are really well made because they assume they will be outgrown.
Paid about $460 for it.
