I wouldn't even worry too much about the paper right off the bat.

Just see if you can get a decent group out of them... also, if you haven't been shooting traditional in some time, your form is going to contribute to your accuracy more than the arrow spine.

I would say that over-spined is better than under, in that you can just put a heavier tip on there and it seems to fix the problem of random fliers.

However, when I considered my arrows to be "over-spined" (remember, 2114 on a 45# bow) I was still doing ok. Once I added the 125 grn tip vs. the 100 grn tip, my groups did tighten up a bit.

So, I would say your 2018 is going to get you pretty close to where you need be. But again, see if you can shoot a few different ones... if I had to do it again, I probably would have gone with the 1916's with 100 grn tips for my bow and may pick some up down the road.
