Northern Mist 68 inch 46@28. My draw is 29. Arrows are Doug Fir cut to 29.5. Brace height is 63/8 Nock height is 5/8. Shoots really great with Ace 160 and Ace 200 glue ons. Here's the rub. Can't tell much difference at all between 55-60 and 60-65 when I'm shooting the 200 gr Ace. Actually, they both weigh in within 10-15 gr of each other. Given that everything is near equal, what is the consideration in one spine weight over the other?

What do your arrows weigh?

A bunch. Each one is between 620 and 640. That make for a high GPI I know. I'm not into speed or target shooting. Hunting only and I want good penetration. Max yardage I'm comfortable with shooting at a critter is approx 15 yds.

You won't be having any problems with those weights and draw weight/lenght. Not sure what you are planning on hunting, but I'm running 4 blades and 2" wide 2 blades through big hogs with my 50@28 Centaur Longbow.
The only real advantage is the higher spin will have more dimensional stability at impact. But probably not enough to ever matter. I'd shoot the ones that shoot the best. :campfire:

Thanks Terry. Mainly hunting deer and hogs. Time to order some shafts so I was wondering which spine since they are both so close. Think I'll go with the heavier 60-65. Its really a coin toss. If I do my part, they both do pretty much the same.

I agree, you should go with the heavier spined shafts. I've always found that I got better arrow flight by overspining a little, even with cut proud of center ASLs. Too, unless you've put those shafts on a spine tester, you don't know exactly what spine they are. If you got mostly high end of one group and low end of the other group, they would be almost identical. Regardless, a few arrows from each group are likely with a pound or two spine of the other, not enough to matter. Tatg's why they fly similarly.
The heavier spined arrows are also likely to be a little heavier physically. And, a physically heavier arrow (because it takes a bit more force to get it moving, which flexes the shaft) takes a bit more spine than a lighter physical weight shaft.

Makes sense. Thanks.

Each one is between 620 and 640.
With a difference of only 20 grains I also say shoot the ones that fly the best. Those 20 grains only make for a 3.22 percent increase, and that's' really not enough to worry about.

Can't say enough good things about the Eberlestock X2.
The type and arrangement of pockest is very useful - especially the dual long pockets on either side. Plus it is set up to expand and carry a large load of meat outside the pack and carries weight exceptionally well. These same features can be used to strap on climbing sticks, rifle, bow, etc. when you need your hands free. All zippers and stitching are extra tough and built to last. Love it!
