What spine carbon to match an Easton 2020 ?

[Gordy]

Love the 2020 shaft, but I'm tired of bending them.  One tough shaft, but would like to try a carbon.  Preferrably soem GT's ....or bemans.

Shooting at least a 30.5" bop shaft and like 145gr min up front.
Thoughts ?   Thanks for the input.

2016 is supposed to be 500 spine.2117 is supposed to be 400.I would think 400 would be closest.Epoxying a 1" piece of aluminum arrow on the front of the carbon shaft and 1/2" piece in front of the nock seems to help durability.The last Gold Tips I built,a 2117 shaft I had fit nicely over the carbon.

Well its hard to compare carbons with other arrows.A 2020 has a .426 spine deflection,so if you compare deflections a .400 spine carbon will be close.Like a GT 55/75,Carbonwood 3000,Beman ICS 400 or if you like the skinny ones a Beman MFX 400.But I find carbons react differently then other arrows,you may have to use heavier inserts and or points.With carbons I start full length and trim and tune from there.Carbons are good tough arrows and really tunable.

Thanks for the tips guys. 400's it is !

JRY309: Did you measure the shaft deflection of both shafts on 13" centers? I don't have a 2020 to spine test but the 400 spines at about 320 (75#) using 13" centers.

JRY309: I shoot 2020's also but out of a 65# Hill style longbow. They also fly great (just slow) from my Wes Wallace R/D longbow at 55#. Guess what I am trying to say is the 2020 may be more forgiving than a carbon in a givin style bow. A 400 spine ST Axis flies great out of my 60# Bear Takedown. Those are skinny shafts also. The CX 250 also flies great out of the Bear. I would try a test kit first or some OP's (other peoples) arrows before investing.

I was just going by the Easton specs and my experience with them as a place to start with.But like I said it is hard to compare aluminum with a carbon.I love 2020's,I shoot them out of my HH Wesley 65# and my Anderson Skookum 68#.I shoot a .400 spine carbon out of many different bows.I shoot 400 spine carbons out of my 58# to 62# longbows and they shoot just great from my A&H 53#@28 ACS.But carbons are a different learning curve and they are so adjustable for bows of different weights.But I would think a 400 spine carbon would be a good choice to start with,but I believe a carbon should be tuned to your bow.It can be alittle tough to get the right dynamic spine and get an arrow heavy enough to shoot.I try to get my arrows 9-11 grs. per pound of draw weight.

Again, thanks.  Was just out shooting a different bow, 61# but more of a D shape (68" original Dywer) and find that my 2018's are better out of that.

If I go 400 I would plan on leaving them 32", and try some different weights first before trimming. I have some varying sizes, plus some 100gr brass inserts.  I don't mind slow as long as it's heavy !
