Spine gurus.....should this work??

[skychief]

I shoot a 1970's Bear Grizzly (40# @ 28") with a 29" draw.

I Bare-shafted with an experienced friend today and found 45# cedars were too strongly spined (nock right).   These were the weakest shafts he had on hand.   Everything we shot had 125 grain field points.

I then tried a 28" (yep, too short for my draw length) 1816 fletched with 4" parabolics (not a bare shaft).   They flew superb.

So, do you think 30" 1816's would work well out of my bow?

Referring to the chart in 3-rivers, it suggest a 2016.   I don't know how accurate the chart is though.

In a perfect world, my buddy would have had some 1816, 1916 and 2016 bare shafts to try.

What size aluminums do you guys think I should order please?

Many thanks, Skychief.

Edited to mention that I shoot 3-under.

a test pack!   no chart is 100% accurate for everyone.

Thanks Dan, but, I didn't see a test pack available in the 3-rivers catalog.

I would start with a 1916 and play with heavier points if they fly left with 125s.

1916s should be about right. 2016s may fly but be heavy for that bow.

I too would try some 1916's.

Thanks all.   I bought a 1816 and a 1916 shaft from a local shop and plan to bareshaft these tonight!

blackwidow at least at one time sold test packs...

Three rivers is not the only game in town    .   There are other smaller outfits that also sell test packs.

Shot the 1816, and 1916 bare tonight.   The 1816 shot like a dart.  We fletched it up and it shot very well with 155 grains up front.

Broadhead testing to come.

Edited to read 155 grains shot well.
