Crap!!![:@]
That's what I was afraid of. Let me backtrack for a minute. If my arrow is underspined, I'm going to have major trouble getting broadheads to hit correctly, right? Also, could that .06 difference result in a visible "corkscrew"apprarance in arrow flight? If so, I now know what my problem is. Another problem is that even switching to blazer vanes to decrease weight, this new arrow is going to be about 50 grains heavier. I don't mind the extra weight, but I've got a lot of sighting in ahead of me.
50 grains seems like a lot. I would think the 7595's would ony be 1-1.5 grains per inch heavier.
And yes, that would for sure cause your arrows to barrel roll and fishtail.
