Dennis,

If it would hurry up and get here([:@]), I have the exact bow you are looking for ordered: 80/29

I suspect you are looking at an Birth Cert. IBO speed (400 grain arrow) of around 288-292 FPS at 80/29.

I'm setting mine up (when it gets here![:@]) with A/C/C 3-71's that should weigh in around 450 grains give or take a few. I would guess with my usual set-up (loop, tru-peep) and the BowTech silencers, that arrow should clock in at right around 280.

Hope that helps.
