RE: Shorter ATA Bows?
Basically a "ditto" on what bigbulls stated...if you are looking for more reassurance. At 6'4" inches with a 31 inch draw length I can shoot a short bow relatively accurately but longer bows make it much easier to make a mistake or two here and there in your shooting form (assuming all else remains equal).
One thing to consider though...height does not always dictate draw length. I can think of several occasions where archers over 6 feet tall were shooting draw lengths of under 29 inches. With a 29 inch or longer draw length I would probably suggest not going shorter than 33 to 34 inches.....35 or 36 would even be better....assuming average shooting ability.
Hope this helps.
