Default Correct Arrow Spine? Please help!

I have a Parker Ultra Lite bow set at 70 lbs, with a 28" draw length. Will these arrows work correctly with my setup? Also, I'm currently shooting 100 grain heads. Will I have to change my heads weight? (My currentarrows are 28.5")

Arrows:Carbon Express Terminator XP Select 6075

Thanks,
Mike

They should work just fine. Just remember to tune your bow to shoot them well.

On my ontarget with a 06 ultra lite 31, I show em stiff. But with 29" and 125gr tips, they come in line.

ORIGINAL: bigcountry

On my ontarget with a 06 ultra lite 31, I show em stiff. But with 29" and 125gr tips, they come in line.
So, if I shoot 29" arrows with 125gr tips I'll be fine.

Thanks for the help!!!

Thats what ontarget says with 80% letoff, if you set it to 65% letloff, that makes it more inline. I would first have the arrows set to 29.5" and try 100gr tips bareshafting, then if that is too weak, you can cut 1" off and heat out your old inserts out of the cut pieces, and clean up and reinstall, and try again at 28.5". Ontarget isn't gospel, but does a good job.

I tried cutting off the nock end and refletching - seemed to be a little easier than trying to get the darned insert out once glued in place.

What Roskoe said. If you're trying a bare shaft you can just pull the nock and cut a little from the nock end till you get the spine you like.
