Hi all,****

** **

I am very excited, I just bought a new Hoyt Altus (weird name IMO but whatever) because my shoulders is not what they used to be, my old bow is getting to be a bit much for me. Also, I just felt like a new bow and the Altus is a beauty.****

** **

Anyway, on to my question: I’ve been shooting 340 spine carbon arrows out of a 1999 Hoyt Raider set to around 65#(Used the raider for some years, then stopped shooting for 10 years or so, started up again 4 months ago). The altus is pulling 42#. My draw length is 31", so I have LONG arrows. (76 cm or so) My question is: Can I continue using my current arrows? I guess they might be a bit stiff, but I ain’t no Levi Morgan, if it hit somewhere in the red at 15m I am quite happy. (I am hoping this will improve with the lighter bow) The point is I don’t care (yet) about perfect arrows, I want to shoot more so I can concentrate and work on my form and process with a bow I can handle better.****

** **

I guess I want to know if the new bow will fire the old stiffer arrows with reasonable accuracy without damaging the bow?****

** **

What spine would be correct for this bow at my draw length? My wife uses 400 spine on her 35 or so pound bow, but her DL is very short. On a long arrow, the 400 might be too floppy?****

** **

Thanks!

    I used to shoot Easton 800 spine arrows when my draw weight was between 20-30#. With my Altus, my local archery shop recommended a 600 spine for my 43# bow. Currently using Easton Venture arrows. My archery friends have arrows which range from 400-320 spines with 45-55# bows.

    I’m not sure how much the length matters beyond comfort/weight shedding since less arrow means lighter arrow. My shop cuts them to an appropriate length that works for me, so if your length works, the important part really is the strength of the spine and giving your old arrows a good flex to check em and make sure there aren’t any cracks. Don’t want anything exploding!

    If you do have a nice, local shop, I highly recommend stopping by to ask for suggestions or getting your arrows cut down if needed!

    Edit: Also, if it helps, I have a pretty short draw length too. I think it’s between 27”-28”. If you check out “arrow spine chart” from different manufacturers, they also have spine recommendations depending on arrow length.

      At the moment I’m using my old 350 spine arrows (shop said that would be ok) and they work. When it is time for new ones I’ll go 400 spine. Thanks!

    Forgive me, I’m not well-versed in compound archery, but I do have an app to calculate arrows for recurve, which will also do compound arrows.

    42# is that at peak?

    With a peak of 42# and 31" draw, then you need an ATA speed rating of 358ft/s to use spine 340. I don’t know if that makes sense, as speed rating is something I haven’t heard of in recurve.

    If you know the speed I’ll put it in and give you a spine. The app I’m using is called arrows and is made by Marcel van Apeldoorn.
