Default RE: Different fletching / tip, similar arrows. 60 gr. = 22 fps faster

I used a calculator http://home.att.net/~sajackson/ballistics.html for the next part:
Arrow 1:
@ 20 yards: 275 fps 65 LB of KE
@ 30 yards: 272 fps 63 LB of KE
@ 40 yards: 268 fps 61 LB of KE

Arrow 2:
@ 20 yards: 292 fps 61 LB of KE
@ 30 yards: 285 fps 59 LB of KE
@ 40 yards: 266 fps 51 LB of KE

I thought some people might find this interesting.
Another reason to bump up arrow weight...look at all that extra downrange KE.
