I bought a dozen Easton A/C/C arrows size 3-60. I shoot a Bowtech Allegiance at 70 lbs with 28" draw. I expected to get my arrows cut longer, but they were too long. Am I overspined? Will that little bit affect my acuracy? Thanks

How long are the arrows, and what weight points? 3-60s should be ok, if not too long, or very heavy points.

I shoot 100 grain tips. The arrows are about 28 3/4".

I doubt that the arrows are overspined @ #70. I have a bow that will crank down to #65, and my 3-60s are cut to 28.5" They fly and shoot very well, even with my bows that max at #61. According to the charts, I guess I should be shooting 3-49s. I can't believe there would be much of a positive difference. It seems that I end up right on the border of spine sizes with most arrows. I usually end up getting the stiffer spined arrows, and broadheads seem to fly well with my setups.

3-60s should work fine at your specs.
