Again, go to a GOOD shop. My dad went to a shop with a good reputation in Springfield and at one point was being measured. Dad has long arms for his height, and so do I. This guy simply would not believe dad's measurements (which are not by any means hard to believe, just a little longer draw than you'd expect) and actually told dad to stop "faking it." He measured several times, then told dad in an exasperated tone that he would make the arrows to the length indicated, but they'd be non-returnable.
I don't know why dad didn't just walk out at that point, but there weren't as many local choices then. He bought the arrows.
When he picked them up, he could tell by looking at them that they were too short. Nope, said the maker, they were perfect. Dad would be grateful once he shot them, because he'd learn that you didn't have to exaggerate the length of your draw to shoot well. There would be no refund.
Dad tried to shoot those arrows, but they just didn't fit his draw. He saved them, though, and I shot them as a kid. They weren't my first arrows (they weren't THAT short) but they sure were fancier than what most of my friends were using for target practice.
