Hey guys,

Tonght I looked at the FOC for the arrows that the guy who tuned my bow let me borrow. Like I said, these are getting about 1/4" high tears through paper, but, on the range, they are flying perfect.

29.25" PSE Carbon Force Dominator 300' s, 100 grain tips, 3- 4" duravanes. The FOC rating for these is in the 9.1-9.2 range. This seems to be very low.

I have decided just to get new arrows instead of messing around with my BlackHawk Vapors. They all need re-fletched. Whoever made them, didn' t do a good job of glueing the vanes on, as I have had some just fly off in mid-flight. So, I am just going to buy arrows that are identical as the ones John let me borrow. They are flying great, and my bow is perfectly tuned for them.

Now, my question is, should I be concerned about spine and FOC if these are shooting perfect. A guy on another board ran these arrows through a program and said that they would be under-spined for my bow, but they shoot great, and, I have read that FOC for hunting arrows should be in the 11-14 range, while these are just barely over 9.

I could use feathers instead of vanes, and that would give me a FOC of 11.6.

I could keep the vanes and use a 125 grain tip, and that would put me at 11.5

I could use feathers and 125 grain heads, and that would put me at 13.9

Or, should I just stick with the plan of buying the arrows John let me borrow, even thought the should be underspined and have too small of a FOC %, since they are shooting good?
