Ok, I just realized I figured for a 30" draw, not 29". At 29" it should do 265ish, for just under 86#s of KE... Probably still more than adequate.
I still don't see that happening at 60 lbs pull. At 70 lbs and 30 inch draw if you had a bow that would shoot at the top end of the listed specs (328) and you use the 3.4 number that Matt provided that would still put you at a loss of 59 fps for a top speed of 269 fps with a 70 lb bow. That is IF it is at the top end of the specs and IF the 3.4 number holds up. So I just don't see a 60 lb bow pulling that off. Not trying to rain on anyones parade I just don't want people to be disappointed when the bows get here and they don't live up to expectations that may have been set a little to high.
PS with my numbers it comes out to 88 lbs of KE with a 70 lb bow which is still pretty awesome.
