Arrow musings

[Bow Bum]

I got ta thinkin tonight....

Is it possible to have two arrows that, given each of their point weights and lengths have essentially the same spine in relation to the bow, but the bow (or maybe me and my form) favors one arrow combo over the other

Arrow #1. 2117 Legacy with 200gr up fornt cut 30.5"

Arrow #2 2018 easton xx75 cut 30.25 with 145 up front.

The 2018's group way better but both arrow combos bareshaft pretty well.

I like thinking about stuff like this. I need to shoot both arrows with BH's to determine which ones group best with a solid business end on them.

Regards,

the 2117 is a thicker arrow then the 2018, with the 2018 you arrow will sit closer to center that the 2117 will.

Sorry but if 1/64 of an inch makes that much difference, something ain't right.

How did you determine that they have "essentially the same spine." My guess is the 2117 is still heavier dynamic spine than the 2018, despite the fact that you have 200 grains on the end.
