A second shameless plea - arrow spine weights

[ComplexCreature]

I know there's another thread or two with this issue but I don't want to thread hi-jack.

I still have my old redlines from 2000 (ish) and I intended to use them again with my new, still to be bought bow.

They are marked as 900's. My draw length is 27.5". I used to shoot 32lbs. This is completely wrong, isn't it?

So can someone explain to me, i words of less than one syllable how the Easton chart works? i think I was previously advised to adjust the weight of the bow for my short ish draw length but I think that means I have over-adjusted! I have the arrows of a ten year old - argh

If you were me, with my half size arrow length (I'm the same with shoes - have to be in between!) would you base length on 27 or 28"? Surely stiffer is better?

Thanks guys!

As par my reply to your other post get down to your local shop.

Take your redlines with you and let the shop help you with arrow selection when you have sorted out your riser and limbs, after all until you sort them out and know what poundage you are holding you can not sort out your arrows, and what your draw weight was six years ago is just a starting point not necessarily what you will be comfortable holding now.

For a very rough idea of what you may need, try the Easton shaft selector:
Easton Archery | Shaft Selector - Target
For "Cam" select "Recurve bow"
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).

A couple of points: if you can't measure your bow weight, there's not a lot of point to this - get down to a shop where they can measure it. And don't assume you know your correct arrow length - "it's what I used to shoot" may not be a good guarantee of correctness.

Best advice is: take professional advice.

aha - that may explain it all - thanks Rik! I wasn't sure whether bow weight was "32lbs" ie what the limbs state they are, or slightly lower, as I'm a bit short. Still doesn't quite make it up though.

My problem is I don't have a car (dealing with it slowly!) so getting to an actual shop is a bit of a bother.

You know, part of me wonders if they've changed the way they size them?! Or is that being daft?! I can't find anything smaller than 780 now My brain hurts!

The Easton website still lists Redlines down to 1000 spine and a quick guesstimate with the shaft selector is giving about a 780 spine arrow for your specs.

Cheers, Jim.

There is no substitute for getting the actual draw weight of your bow established. The rule of thumb is every 1" of draw length has a 2lb effect on the draw weight. So if you do not have a long draw you could be quite a number of pounds down on the 32lb marked on the limbs which are measured at 28" from a point 1.75" in front of the neck of your grip. Also there can be quite alot of variability in limb weights anyway, the 32lb figure quoted will be nominal. To give an idea of how much difference there can be I once swapped from 30lb limbs to 32lb limbs from a different manufacturer, when I measure the change it draw weight (without adjusting the bow) it was just under 6lbs, my old limbs were below spec and my new ones above spec. There may also be some softening of the limbs with time (but thats just a guess).

If you can get hold of a draw weight gauge, set the clicker to your draw length (assuming you are using a clicker) and check the draw weight as you pull through the clicker. Failing that get your local archery shop to weigh it for you.

But a good guess. I don't have the figures handy, but I believe Vittorio measured the weight loss of some pairs of recurve limbs over time. IIRC there was a tapering profile over time (the loss became more gradual). I can't recall if the loss was strictly time-related or more accurately use-related.

Things may have changed a bit since 2000.I had a set of redlines last year(good arrows) but had to sell them because a lot of places now ban carbon only arrows.Especially clubs that shoot on school fields

Fortunately, mine hasn't. It owns the land, so can do what it likes.

I do realise I may be stuck for shooting elsewhere though! I may not buy the same again as I'll probably move county soon (again!!)
