I currently have two sets of acc arrows. One set are 500 spine. The other ones are 620.
As a quick and dirty test today I shot fletched and bare shaft at a target 20 yards away. The Fletcher went in the middle regardless of the spine. The 620 bare shaft went to the right and slightly higher (7 or 8 on a 60cm face). The 500 bare shaft went about the same distance to the left.
So to me the 500 is a little too stiff and the 620 is a little too weak, but neither is massively out. I think I added weight to the 620 points to make them weaker when I got them as my bow had weaker limbs then.
If it makes any difference the 620 bare shaft has better arrow flight than the 500.
The arrow length is 30"
Anyway the reason for this was I was considering getting some x7 eclipse arrows for indoor shooting and needed to work out which spine would be best.
The easton site suggests two spines:
2212 505
2114 510
I take it that the 22 is a wider diameter? Which I take it would be better for line cutters.
The 2212 is 8.8 gpi and the 2114 is 9.9 gpi. What is better for indoors shooting?
Thanks
