That's just it, we don't build them shorter to compensate for that extra few inches, like Will measured. If we want 64" ntn, that tape is stretched straight across on either bow.
I'd also agree with most, they shoot like all other similar bows to me as well. But, I would also say that I could shoot 10 osage flatbows from the same builder that are 45-52# and 63-67" and they'd all feel the same to me as well. So is that a good measuring tool? Probably not. We need a speed checking macheen and two very like bows in length and draw weight and shape, less front profile of course.
