    More arrow spine questions

    Guys/Gals,

    As you may have seen, I am moving up from a Black Douglas with hex 6Ws 38# @ 28", 70"bow. Currently shooting 500 spine Easton Powerflight which match quite good.
    My Covert Hunter when it comes will be the same poundage and size but using Hex7.5h limbs.
    My question is thus, will I be able to stick with the same arrows or will I need to change the spine?

    Thanks for your input

    Field? Target? Sighted?
    Are the new limbs similar poundage?
    Very little information supplied.
    Unless there is significant poundage change I don't s'pose it will make the slightest difference once they are 5 yards past the bow, and very little before that.

    Ha! Sorry Del, you have no idea here...
    Hi BobbyG You'll find a Covert packs considerably more punch than your Hex6s. Del is correct in that it is impossible to offer much more than that without your bow length, limb poundage, and draw length, as well as the point weight you have in mind. I have ILF 7.5s which need me to be 1-2 spines up on the Easton charts. The custom bolt down fit of the CH will be faster still. And I still get better sight marks out to 90m+ than with my Hex6.5s.

    I think "no idea" is a tad strong...
    He doesn't say if he's target or field shooting!
    I think the whole spine thing is vastly overstated especially with bows that are near centre shot.
    The other day I was field shooting my 45# primitive (arrows 35-40 spine 5/16" dia), in the group was a guy shooing a 60# carbon or glass faced AFB, he was shooting arrows just over 11/32" dia in the "highest spine I could find"... we both had 100gn points.
    We had been discussing spine and near the end of the shoot we were forced to wait and I suggested he tried one of my arrows (with the agreement of the rest in the group)... It flew just the same as his arrows striking at the same point.
    I do agree I have "no idea" about target archery tho' ...

    A tuned bow is a tuned bow, be it used for field, target clout or flight.
    The only difference when you're a CH owner is you might use a heavier shaft with a heavier point for field as you'll need to reach a shorter distance and lighter shaft and tiddly point for flight. All tuning does is give you repeatability and predictability. One arrow shot, landing on a target just once is neither repeatable nor predictable.
    An important factor to consider is Border's minimum gpp recommendation. Too light will invalidate warranty.
    When you've spent well over 1000 on a bow, getting the best match of arrow to bow to archer is extremely important. Otherwise you might as well stick with a bent, well, stick
