Arrow Choice Advice Needed

[Morning]

Having bought my arrows (Plat Plus 1716) to go with 30lbs limbs, I have reduced the poundage (to 28lbs) and shortened the arrows by an inch (now 26") and now find that my arrows are far too stiff.

Yesterday I tried various other arrows that were much closer to what I should have (Plat Plus 1616, Carbon 920 and ACC 2:1500).

I also have a shooting distance issue - I can hit 50yds find, but doubt that I will be able to hit 60yds without reversing my sight, so arrows that would increase my distance would also help.

I have looked on the Eastern charts which puts me on a Y6 in the youth and T1 on the adult scale (I am an adult, but pull 28lbs on 26")

Y6 would be:
Plat Plus 1516
X7 - 1612 or 1614
Acc 3-00

T1 would be
Plat Plus 1616 or 1713
X7 - 1712 or 1714
Acc 2L-04 or 2-04

My questions are:

1: How reliable are the charts - should I look at the T1 or Y6 values?
2: How much difference would ACCs give over X7s - is it worth it at the kind of arrows weights at this end?
3: How much difference would there be between the X7 1612 and 1614 - would one be that much better/worse or is it more a fine tuning thing?

Thanks

Charts are very very reliable but if there is a choice of two spines I'd recommend the stiffer option (personal preference).
There is a huge difference in sight marks between equivalent spine'd ACC's and X7's
Both 1612 and 1614 should come out of your bow reasonably OK, and are well within possible adjustments to bow weight and pressure button settings.

I have to disagree slightly, the charts are a very rough guide, and are not really that accurate.
They don't take into account of variations in the riser/limbs/stabilisers etc.

However, it is always better to sway towards a stiffer arrow, as these (as long as they aren't too stiff) can still be tuned to the bow reasonably well. However, an arrow that is too weak cannot be tuned with any accuracy.

Cheers, Kae.

Although I am using A/C/E shafts, I have found that Easton Charts are very reliable. Further more prefer to use stiffer shafts and tune them (using the plunger) rather than using less stiffer shafts.

In talking about arrow choice, people say choose a stiffer spine rather than a weaker spine. If arrow length is fixed, this means that given a choice we should be choosing a bigger diameter and/or thicker wall arrow. Comparing these is difficult (sometimes thicker wall, smaller diameter is stiffer sometimes weaker depending on the ratios) so to decide which arrow is stiffer, I understand that we should just be looking at the spine measurement. Is this right?

( ie in the examples quoted here for groups T1 & Y6, the following progression shows weaker to stiffer arrows:

X7 - 1612, 1614, 1712, 1714
75 - 1516, 1616, 1713 )

I have just checked on the 2006 shaft selector, you can download it from www.eastonarchery.com on the downloads page. If you have range issues then the lightest arrow for your weight and draw lenght at a reasonable price is the Redline 900, but the draw back is that it is an all carbon arrow. While you are on the downloads page you might want to down load the easton tuning guide as well.

First you have to decide what type of shaft you will be using eg. for target shooting (outdoors) Easton’s X10s and A/C/Es are the most popular. Then according to your draw weight and draw length you can use either the Easton charts or Shaft selector to find the right stiffness of your shaft. For selecting a stiffer shaft all you have to do is to move down the scale i.e. from 620 to 570. Personally I shout A/C/Es 620 whereas the charts indicate 670.

OK, when you are this end of the spine chart, the options are not that much. Question is do you go with a narrower arrow with a thinner wall or thicker arrows with thinner wall when looking at Ali arrows. X7 and XX75 seem to have a few options so advice in this would be useful.

Anyone know if Triples go down to the 1300 spine area? And given the comments on Triples spines not being accurate, what would you suggest.

Morning was shooting some 1500 ACC's the other night. They weight nothing and could be used as knitting needles. Complete arrow is the same weight as most peoples shaft. ACE's and X10's don't seem to go down this far, and to be honest, is there much room for weight benefits?

Triples go down to a 1200 spine, and at that spine are very light indeed.

I didn't have a problem with the spine charts with my triples, the charts say 700's will tune *just* tho be a little stiff, and they tune perfectly well for me.

In my experience, the charts are deeply rubbish at our drawlength/poundage. I say this every time, but what you should be looking at is the easton spine/weight comparison chart. Its on their website. Find your perfect ali on it, then go left in a horizontal line. The carbon nearest that (ie with the same deflection) will be the right one for you.

That said, seeing as you seem not to know your perfect ali with your current setup that chart is pretty much useless too. Happily though, your arrows are exactly the same length, and draw weight exactly the same, as my set up. Which means that your perfect ali arrow is probably 1516 XX75 (1514 or 1612 X7), and your perfect ACC therefore the 3L-00 or the 3-00. I have the 3-00 because I need my arrows on the stiffer side. See if you can try a 1516 ali of the right length - if they are right then either of the ACCs I mentioned should be fine. Remember though, if you go to try arrows at a shop they will refuse to cut them down for you to try, and so when you buy them and they are cut down, they will react stiffer. In other words if the ones you try seem only slightly too whippy, they'll be the right ones when they are cut down.



Regarding your sightmarks, having carbon arrows will make a difference, as even in the smaller sizes they are lighter than the equivalent spine alis. With ACCs you should reach 60yds and beyond with ease. I manage 70m fine with the same poundage/draw length. Feel free to PM me if you want more info. And if you're really desperate, I could arrange for you to try my ACCs. I'm going to sell them soonish anyway.
