A second shameless plea - arrow spine weights

[addo]

Your half way between 780 & 690 spine.If you can't get to a shop then go for 690 spine(the stiffer of the two sizes) with 100 grain points and fairly small fletches.If you don't use a clicker you can buy the arrows 1/2"-1" longer than you need which will weaken the spine a bit more.If this makes them too weak then just cut the extra off and it will stiffen them.

Easton Archery | Shaft Selector - Target

Your bow weight is "actual bow weight" (that is what you measure it at, when you are at full draw).
Your arrow length is from the throat of the nock to the end of the shaft (not the end of the point).

.

interesting as when myself and others in the club we use the chart as follows.

bow weight we dial in what the poundage is measured at 28" the AMO

then agree with arrow length,

my specs are as follows

40lb @ 28"
44lb @ fingers
30" arrow

using your method the chart suggests i use a redline 460 spine
using my method the chart suggests i use a redline 520 spine

now i have read on this forum that alot of people suggest the easton chart suuggests all too often a too stiff an arrow, using your method i would agree, but using my method the tuning is spot on.

i know because another archer in my club uses 31" 460 spine redline. even with the extra length they came out way too stiff for my bow, yet the 520 spine the chart suggested using my method are perfect,

This method was taught to me by my coach JOHNSKE on here who has over 40 years experience in archery and was also a supplier of equipment to archers over the same period as well as reaching State coach, so he has seen the differing easton charts over the years and noted the changes and therefore understands how they work.

all i can suggest is to try our method

I thought, on reading it now, that what TropicalShot says is right. I think the other way is how I came out with 900s, but I'm sure it was right at the time. Oh well! Will definitely be getting some good advice, either from coaches or shop, but I am really enjoying the discussion anyway!!

Am i right in generally thinking that slightly stiff is better than slightly weak?

slightly stiff can be obtained adjusting poundage but you have to have the correct spine to start with,
a whole spine stiffer will be very hard to tune if you done have the poundage adjustment to do it

Well, you can ignore Easton's instructions if you like....

The notes on the (paper) charts say something like "Actual peak bow weight should be measured at your correct draw length".
It has been contended in the past that Easton's charts tend to suggest shafts which are too stiff. But remember that's better than shafts which are too weak...
But thinking about it, if your arrows are within +- a couple of inches of 28 inches, then the draw weight you measure at 28 inches is likely to be within a few pounds of your actual draw weight, so will probably (unless you are at the edge of a section) fall within the same section of the chart as measuring actual draw weight. Could be up or down a spine, though.
In reality, spine charts are a place to start, not gospel.

IMO,that is correct.I think the idea behind that way of thinking is that after a couple of months of shooting you may feel the need to up the poundage a bit,which would make the weaker spine too weak to tune but would bring your slightly stiffer spine into the ideal.

I had a set of 460 redlines which were way too stiff(the shop didn't have correct spine for me).I needed 520's or even 600's.I brought them 2" longer than needed.After 3 months i had upped my poundage twice and i had shortened them twice.They were a bit whippy at first but at the time of me selling them they were spot on.I'd still have them now if it wasn't for the ban.

I wouldn't recommend doing it the way i done it because its a lot of messing about.I was too impatient.But it does show that a very stiff spine can be tuned with a bit of understanding.Recurve bows are very adjustable and seeing as you will only be,at most half a spine out,you wouldn't have any problem at all
