Chris is dead on about AMO specs, but a lot of bows don't go by AMO specs. I've seen it go from 1.5" to 4" shorter for longbows, 2.5" to 6" shorter for recurves. The Pearson's I've owned did fine with a string 4" shorter. 12 strand dacron for that one. Most likely it's going to settle in some, but a few twists will fix that.
