This is similar to what I go by. I take my draw length and add the brace height. I am near 30 inches and my bow has 7.5 inch brace height. My bow has a 37.5 ata. 30+7.5=37.5 I shoot a specialist. It is better to go longer than shorter.at least 5 to 6 inches longer than draw length for hunting and 9 inches longer for target .
We must be the only short axle-to-axle shooters on this thread. 31' is about the maximum that I can tolerate, preferred length would be around 28'. It's a shame that few manufacturers produce bows this short anymore and I'm still looking for a good deal on X-force SS, which at 27' length produces 348IBO. String angle matters little to me, as with a release aid there is no finger pinching at all. With a sub 28' bow you can do things that you can't with larger bows for instance pack it into a normal suitcase for travel etc. The larger bows are just too bulky and unwieldy. Not much shoot-ability is sacrificed by cutting down on length. Just my opinion.Got my first 30" bow in 2000 I think. I am a 30" draw. I just liked how it handled. In the 80's and 90's I would sit in my stand and look at my 36-42" bow and think, why doesn't someone make these things smaller. Now I have bows ranging from 22"-31". If I only shot targets for money, I would shoot a 34"-36". For the time being, I shoot 3D with the bow I plan on killing animals with.
