DH21 what you could do (if you have a proshop to shoot them at ) is shoot each one of them with your eyes closed and see which one feels the best. You will be supprised at how much difference you will feel shooting like this. This is what I had to do and it really helped.
I'll second that! And better yet , have the pro shop tech blind fold you when he puts the bow in your hand so your not influenced by brand , model , or price tag.
Just pick the one that feels best!
