Spine Uniformity in Carbon Arrows

[bigbadjon]

I was sitting at my desk last night running random arrow shaft I had through my spine tester. I had several random one offs and a couple sets. The first one I ran was a cheapy Redhead arrow I killed my first deer with and it had a 3 pound variance from the stiffest side. The next one was a Carbon Express that has 7 pounds of variance. I have full half dozen Victory V1s that all varied by 5 pounds but some varied higher and some lower. I didn't have a carbon Easton but used a 1/2 dozen FMJ and they were the same spine all around and matched within a pound for the whole set. The Victory arrows could all be spine matched by indexing the nock but if you inadvertently turned it the spine difference may be noticeably.
Does anyone know if there are any options besides Easton or Carbon Tech that offer uniform spine around the entire shaft?

I have found Easton's to be the most consistent. Love my Axis Trads

Last years I found out that woodies are more consistent in spine then carbons.

well this helps me alot...i just tryed some carbon express this last week and hated them right from the start...some were good some went high some low changed to cock feather in then thing changed again...tryed diff point weight along with every other normal tuning steps and still hated them.  

SOOOOOOO i went back to woodies...no problems

Before it gets too off track I make wood arrows for myself that are matched to the pound in both spine and weight and conceding that I cannot sound humble by saying so I do not believe anyone makes arrows better than mine. That said it is expensive and sometimes impossible to make wood arrows that perfectly match and I am interested now in shooting carbon shafts. I know Easton and Carbon Tech advertise they have cencentric spine uniformity and was curious if any other manufacturers incorporate this feature.

i used to use gold tips but found they have a stiff side. simply supporting the ends of the shaft between two tables or something and rolling the shaft with your hand with downward pressure in the middle you could feel the stiff and weak points.

i shoot axis now and they don't do that.

I wonder how they get the stiff spot out.....

I know at one point many of the companies where using rod building ideals (mandrels) or actual rod building companies themselves to make shafts.

Its to my understanding that Easton shafts are pulled onto a tubular shape and have no seam at all. Carbon Tech is apparenty layed up with balanced seams around the shaft.

Three Rivers Trad Only are very consistent all around the shaft and from shaft to shaft they are the same spine. Each batch the same spine every time I order.  Excellent quality.
I think I finally found a bad one this week. It was an old one, reflected multiple times, and it might have been abused a few times!

I never looked for consistency, shaft to shaft, but I have found that they don't always spine as marked.  Three different manufacturers showed different reading for same spine ratings.  All three I checked ran heavy. One .300 spine hit .260
None went less than indicated spine deflection.
