Just started shooting my BT Captain. My old arrows are:

7595 GT Pro Hunters 27" with 100 gr insert & 100 gr points
Blazers
S nock
Total weight 481 gr

I know these are probably too stiff but please read on.

My new Captain is 60 lbs at 27" and is only spitting these at 234 fps. When I select generic compund and enter my data, AA returns an IBO speed of 302 fps.

Does this mean that I am missing some efficiency through cam timing, overly stiff spine etc?
