ski6jones, I settled on
.798, 2.514, 6.855 tips and 30" ft binding and 8 degrees wing. I'm on D3 bindings. This setting feels best to me. Very stable and forgiving but still easy to get wide. I'm 210#, 34mph.
68.5 Elite Stock is binding 30 inches from tail, 6.855 (using tips of caliper) length, 2.510 and .795 dft (distance from tail). Drew Ross gave me a starting point of 6.850 tips, 2.510 and .800. Chet Raley told me to start at 6.735 jaws, 2.515 and .800. I hope this helps.
