Can someone tell me if they go by AMO specs (3" shorter), or if they have their own formula?
Chad
All of mine have been AMO.
Chad,
remember the ones you made for me for my 60" Griffin ? The first ones were either 1" too long or too short, cannot remember ??? Seems like it was too short and we had to make up a 58" string. I brace mine @ 7.25".

Mine are also AMO standard.
Yup my 64" takes a 61" string
There was a thread on here recently with John McCullough's phone number. Anyone have it?
Chad, here's his # 517-626-6365. I'm going to say around 2" shorter then bow length on the griffins. Back when he started building them , he had me make a couple 450's to try. Just a guess.
