    I just got a new batch of Carbon Express Predator II arrows. They are cut to 29" shaft length 29.5" overall length. Fletch is a 4 degree right offset. I am currently shooting both 100gr field points and G5 Montec fixed blade broadheads. I am looking at maybe switching to a 125gr FP and BH.

    Is this possible or will it toss the spine too far out of wack for me to shoot out of a 29" DL with 65-70# DW?

    What is the spine on your arrows. Depends if you are on the low or high end for your draw weight now.

    got the program you suggested Hoosier. Helped a lot. after a little adjustment to my bow I can use either 100 or 125gr tips and be in the spine limit. Thank you for the link.
