    Hey guys I shoot black eagle rampage 300 with a 27 inch draw and shortly under a 27 inch arrow at #70 I'm right on the line between 350-300 should I got with more spine or less spine for better flight out farther ?

    Go with the 300 and put a brass HIT insert in the arrow to break the spine down a bit more and give you more KE.

    Well I was thinking of ordering new arrows because I already have 300 and I thought I needed 350 can I throw a 125gr head on it instead of pulling inserts out ?

    If you have too, err on the side of a stiffer spine.

    I found myself in a similar position. Right on the line between 300 and 340. The chart instructions say to round up the 29.5 inch arrow length to 30 which then calls for a 300 shaft, but the box says that they are good to 70 pounds.

    My solution is to leave them the alone and try them out. I have enough extra length that I can shorten them my a couple inches if need be.

    I like to go heavier. Quieter, more kinetic energy are both factors for me and on the line, I'm going heavy.

    are there any downsides to being on the stiff side ?

    I'd go heavier. Heavy arrows seem to be the trend these days.

    I agree with the others. Go heavier.

    It is hard to be over spined, easy to be under spined. FWIW I shoot the same Axis 300 w/50gr insert from my 70# and my 60# bow. Both bows shoot them great.

    If I was on the edge I would go stiffer. If you have the 300's already going to a 125 tip would work. I actually would prefer it.
