Need help choosing arrow

[Flingblade]

I have been playing with Stu's calculator and am trying to choose between two different arrow set-ups.  A 2219 with 165 grain head would weigh 626 grains with FOC of 13.5%, speed of 170 fps and a 2020 with 125 grain head would weigh 558 grains with FOC of 10.9% and speed of 179 fps.  The energy is virtually the same for the two.  Should I go with the heavier slower arrow with higher FOC or the lighter faster arrow with lower FOC?  Also, I wish the calculator had the Arrow Dynamics shafts listed.  Any advice would be appreciated.

I would go with whichever is more accurate from you and your bow.  It seems either will do the job . . . but only if placed where it needs to be.  

One additional thought would be that, for me at least, flatter trajectories are easier to guide through windows in the cover.
