RE: Disgruntled Wifes Dilemna....
When it was time for my girlfriend's new bow we went through the same thing- no shops stocked anything in her range.
When I would go to different shoots around the area, we would get talking to other women shooters and most were very kind and would let her shoot their equipment. We happened to find a shop about an hour and a half away that had a woman co-owner who let my girlfriend shoot all of her personal bows. Very nice of her.
It may take more leg work and time, but you can find some bows to shoot if you look hard enough and find the right people. Local shoots are a great place to meet new people and check out everybody's equipment.
Just be considerate of when the person is shooting- many are very kind but would rather let you shoot their equipment AFTER they have finished thier round/course.
Best of luck!
