RE: String Length
I believe it's 2" shorter than the bow, or you can give the string maker the AMO length and they should know how long to make the string. I reckon there are a few places on the net you could get flemish twist dacron strings, just do a search for them. Chad (LBR) makes them. I think he's off hunting moose right now, but no doubt he could give you a run down when he shows up again.
God bless,
