Look at what you personally want the bow to do for you. The type of shooting you do the most of should be considered first. Long range shooting requires a mid to heavy bow with more brace and ATA. Shooting at called in turkeys out of a blind on the ground might find you looking at a 29 inch light weight bow because of all the other things you have to carry in also. 3-D' s need forgiving accuracy and speed for shooting outdoors and in possibily high winds and rain. They will all work but some will do better in certain cases.
