What spine?

I know little to nothing about carbon shafts but have decided to try some. I would like to use these arrows out of both bows. One is a blackwidow psa III 52# @ 28″ I draw to a little over 29 and assume that its about 55lbs. The other is a 60# D/R longbow at my draw length. The carbon express piledriver shaft with weight forward design is what I am looking at, with a 100gr brass insert and 200gr broadheads. Will a 350 spine be what I need or will that be too stiff?

Thanks Rogue

In my humble opinion, the weight forward design is a gimmick. It doesn’t really do much to affect the front of center for the arrow.

If you are interested in increasing your front of center with a carbon arrow, the best way to do that is to find a shaft that is as light as possible for your required spine. Then when you add your insert and heavy point, you will be moving the FOC in the right direction.

I hope this has persuaded you to look towards a different arrow. But if not, to answer your question directly, I think you need go no higher than a 250 spine arrow.

I agree with Steve. These companies saying their arrows have a weight forward built into the design are full of bull snot. The only ones that are actually built as a weight forward are the tapered shafts, such as Grizzly Stik.

Sorry for the double post apparently I need some more education in carbon arrows and computers.

Thank you for the replies I guess I should have mentioned that I wasn’t as concerned with the weight forward so much in the shaft design, as the total weight of the arrow itself. These shafts are 11.3gpi and I am used to how heavy shafts perform.

I will also admit that around the web there are several pics of thumbs with half an arrow sticking through them so I am tempted to lean to the stiffer side if I go carbon. sorry if I wasnt as clear as I could have been in the first post.

Rogue that picture which is probably one of two taken while both individuals were in the hospital ER, one was from his arrow bouncing over off his modern rest ie for compound bow, and the other was from a damaged carbon arrow exploding off the shot. Both of which are quite educating in themselves, as we use them teaching Bowhunters Education as a warning to always check your carbon shafts for damage by flexing them, and also not using an under spined arrow on a high speed compound bow.

I haven’t seen this occure from shooting carbons off of a traditional bow as of yet.

Rogue,

Carbons are great. Check out my posting “EFoC and Carbon Arrows”. Anyway, if you want a high FoC arrow go with a lighter massed weight carbon arrow. For a 52# bow a 250 should be the ticket. I’m shooting a 53@ 28 and pull 28.5 (so I’m in that 55# ballpark also) and my terminator select 45/60 work great. They spine a 0.397″ of deflection or 79.4#. Any arrow around 0.397 will work for you.

Any more questions let me know.

Rouge,
For those bows I’d personaly go with a 400 spine,and tune each bow to shoot them as a 5Lb spread is easily adjusted for at the bow.
Point loading,,,I only use it to soften carbon arrows due to their virtualy always being to stiff at the GPI I want to make my required end wheight in the correct spine.
JMHO,but if you want better arrow flight,use a tappered shaft,not extra wheight up front,,by doing this you end up with a more forgiving arrow with a wider range of bow wheights it can be shot from,and you won’t suffer incressed tradjectory and reduced point on distance.
