    The spine depends also on your draw length and the point weight. With 26" DL a .400 could be okay but with 31" DL a .340 would be better, maybe even a stiffer one.

    At 70# you're in need of a 340 spine with anything from about 25 to 27". Get to 28-29 and you definitely need a 340 spine. Anything over 29" I'd recommend a 300 spine.

    Of course there is a way around some of this. NOthing in any rule book says the bow has to be shot right at 70#. Part of tuning is using the limb bolts to adjust poundage. If you have to back it off then so be it.

    Poundage is just a number and as such is all in our minds. It's the ego thing.
    You're not less of a man if you need to adjust to 65# to get good arrow flight. In fact, that makes you smart.
