I have an unusual question. I have a martin bengal with nitrous cams. The standard bengal with the m-pro cams claims a 32" ata with an IBO of 310fps. My bengal with the original strings had an ata of 33". My dealer made a custom set of strings for me that brought my ata down to 32 3/4". I gained 10fps but only 2 lbs draw weight. My question is since the bengal was designed for 32" ata would that make the limbs their most efficient ant that ata? It seems to me I gained quite a bit of speed with little draw weight chage. Since this is a custom bow I would think getting shorter strings[all three] to bring the ata down to 32" would gain me even more speed without the poundage going way up. Any thoughts?
