Spine weight is based on a 28" draw bow and 28" arrow length. If you happen to shoot a 28" arrows and your bow weight is based on 28" you simply use your bow draw weight as your spine weight. If you shoot a arrow that is shorter or longer than 28" but your bow draw weight is based on 28" simply add 5# or subtract 5# of spine for each inch over or under 28" in arrow length. If you shoot a arrow longer than 28" add 5# of spine per inch over. If you shoot less than a 28" arrow, subtract 5# for each inch under.
WHAT IS THE TURNAROUND TIME?
The normal turnaround time is 2 to 3 weeks. I make every effort to have them to you within that amount of time. On occasion it may take a few days longer. Quite often it will be less. I make all orders in the order I receive them.
