I tried a 2018 bareshafting and to get it perfect I had to cut it to 28 3/4 inches, my draw is 28. I am using a 125 grain point. I know I am being really picky, but I want my arrow to be 29-29 1/4. and I want to shoot a 125 grain head, so my question is what spine in aluminum would be just a hair stiffer than the 2018. I am shooting a 50# @ 28 " Treadway Longbow.
I would with the 2117! The all time favorite! :saywhat:
According to the Easton chart
2018 has a deflection of .464
2020 has a deflection of .426
2117 has a deflection of .400
I would try a 2020.

Yep!!
I'm having a hard time seeing you get good flight with a 2018 with a 125 grain broad head on a 50 pound bow :saywhat: ..... are you cut past center on that bow?
i could see a 2016 working better for you at 50 pounds 125 up front. i don't think i'd go stiffer unless get more weight up front.
i was using 2018's cut to 29" with 200 up front on a 57 pound bow and getting excellent flight. i draw 29" and that bow was cut past center too.
i think you are going the wrong direction on spine bro...
I'm thinking ... "What Kirkll said ... " is on the money unless your bow is cut way past centre
But of you do need 'stiffer ' 2117 0r 2020 would do it .
Ditto what KirkII and Ben say.
2020 would have been my reccomendation.

If the bow is cut way past center and if if you want a slightly stiffer arrow since you state the 2018 was working well for you at 28 3/4", then a 2213 is a hair stiffer.
2018=.464
2213=.458
Kirkll,The bow is cut to center, I have 2 Treadways and they like a little stiffer arrow, or either its something I am doing in my form, either way, I bareshafted the 2018, it showed way weak at full length, I started cutting it a 1/4 " at a time, amd ended up perfect at 28 3/4. I am not doubting you, I would say according to " charts " the arrow is too stiff. I just know what I saw in the testing. Thanks for the advice
I shoot the same arrow out of my 56#.....for me my bow likes it under spined so I will go 200 plus....but if u do want to only shoot 125 give it a try but from what I have experienced I get eratic flight unless I weigh down the front.....remember the shorter u cut the arrow the stiffer it becomes so on estimation u would shoot around a 30 inch to soften up the 2018......to handle 125 and that even might be too light
Good luck
The 2020 is the most durable aluminum on the market.
I agree with Bill.If you do need slightly stiffer than a 2018,I'd jump on the 2020's.They are tough and thinner diameter helps too.
I agree on the 2020 arrows being durable and they also give you a bit of weight.Great arrows that are tuff to tear up. very next thing to carbons.RC

well the only thing i can think of is that is one very fast shooting bow you have there.... getting that weight spine flexing with only 125 up front is unusual.... :saywhat:
Why don't you try adding some weight in the front, maybe 50g brass inserts or heavier adapters. The 2018 @29+" should fly great with 200g up front.
I am having the same problen with my treadway bought 3 dz of 2018 and I have to go too short I draw 28 and less than 29 will not help with the broadhead
