Hey TFOX, since you' re bored...
How ' bout running this through your program to see how the spine match is-
Bow- Diamond Hornet solocam, set at 28" draw, 70#s, shooting off the string (TRU speed nock with scott mongoose release)
Arrow Shaft- ACC 3/49 with acc inserts, unibushings and g-nock, off the top of my head I can' t remember the shaft length, hopefully you can back track into it.
Tip weight- 100 grain
Fletch- 3 4" feathers, offset, not helical (don' t know exact degree of offset)
Finished arrow weight, 375 grains.
Anything I missed?

Sorry I didn' t see this untill now.I am on my lunch break and don' t have time right now but I will try to get it this afternoon.
If you can, measure the tru draw and the arrow length.Shaft only,no nock.
Also the ibo rating would be nice.

IBO is 318. For what it' s worth, it has a bowtech licensed cam, the one BT were using for their solos just prior to the infinity cam. Diamond calls it the Saber tooth post feed cam, but it' s identical to BTs from what I' ve seen.
Arrow shaft= 26 13/16"
Insert= 1/6" thick
Uni-bushing= 1/4" thick.
Arrow from outside of insert to outside of uni-bushing = 27" .
Forgot to add- Draw is 28" , measured to throat of grip + 1 3/4" , amo standard.

Rangeball,I ran them through the program and provided that the bow performs the same as the program says it might the arrows seem to be too week.I used an amo draw of 28" .measured to the grip that would be 26.25.
If you have access to a chronograph you can find out how close they are.The program said you should be shooting about 276 fps but this is just an estimate.Some bows are closer to the program than others.
3-49 @ 276 fps were too week
if you added a loop and shortened the draw 1/2" to compensate and dropped to 68# the arrows will be perfect.They would be still be shooting around 268 fps.
If you don' t want to change the bow then a 3-60 is what you need.You would also need to go with a 125 gr point.You should still see about 262 fps with these arrows.
If you are seing closer to 264 fps with those current arrows then they would be pretty close as far as spine is concerned.
If my #' s are correct
current arrows with a week spine(not extremely week but more than what I would be comfortable with)
ke@ bow 63.3 276 fps
ke@ 40 yards 54.3 255 fps
Current arrows with shorter draw,less poundage and a loop.
ke@ bow 59.7 268 fps
ke@ 40 yards 51.1 248 fps
3-60 arrows, No chaqnges with bow and still shooting off the string.
ke@ bow 65.1 262 fps
ke@ 40 yards 56.5 244 fps
I can' t stress enough the importance of finding out how the bow is performing with a chrono before I made any changes according to these #' s.If you find them to be close then I would definately do something.
