Originally posted by Orion: I've been shooting sticks for about 60 years now, and the AMO standard has been around for quite a while. No need to get your undies in a bundle. The 26 1/4 measurement, plus 1 3/4 will be very close to measuring to the back of the bow for most bows because most bow riser throats are about 1 1/2 to 2 inches deep. For 90% of the bows out there, the AMO measurement will be within1/4 inch (or closer) of the back of the bow measurement. That translates into 1/2# of draw weight, or less. That's close enough for me. Or stating it another way, either one is close enough for me. Don't sweat the small stuff.
