Spine weight of Carbons?

[Cupcake]

For a 55# at 28" recurve those 150s are probably not stiff enough.  My 49# Gamemaster, which I draw to 30" soit is about 55#, likes 400 spine with 200 grains up front and cut to 31.5".

A 500 spine shaft at 30" with 100 grains up front was still way too weak.

The 150s are a .487 spine so i think they will be very close to 500s.

Good luck.

I've got some 45# limbs for a Morrison Cheyenne. That would be a better match it sounds like..? The conversion that I was given put the CE 150s at almost 65# spine weight. So I thought they would be ok with a lighter tip weight for target shooting. The CE 250 are about 84# spine weight. Which would be good with heavier tip for hunting. What do you think?

The centershot of the bow and how you shoot effects the dynamic spine.Everything effects it. :)You just have to start long and find out where you need to stop cutting for things to be perfect.The 150s will work from your bow if you are not locked into certain arrow lengths or point weights.That is when people run into issues with carbons in there first attempts.jmo

Snag---My longbow needs 200-205 grain heads to bend CE 100's around enough to fly well---this is a 60 lb rated bow that draws 56 @ 27 inchs---the arrow are cut to 28 inch and have 3 gr/inch weight tubes.

If you haven't read the tuning arrows article in the latest TBM, you are missing out. It is a great summary as to the why and why not of arrow behaviour, and how to tune arrows to they fly correctly. Also, your form consistency will change how the arrows fly as well. So try to be consistent eh??..good luck. Also, I would agree that unless you use a lighter point, the 150's will probably be too light.

I will be using the 150s with a 45# bow and some 250s with a 55# recurve. That's kind of funny that you mention the TBM article. I just read it through again today.
