    I believe those are a 400 spine and with your specs I definitely would not go any heavier on your tip weight.

    However something doesn't jive with your total weight you mentioned in your original post 350 gr. At 8.4 grains per inch that puts you at 243.6 just raw shaft. So if you have a 100 gr. tip blazers, inserts and nock that would put you well over 350gr. Even at a 85 grain tip would be still over the 350gr. Just bringing this up because your FOC just might be more than you think. Maybe you had a number off on your calculations.

    That gives me 10.3% FOC.

    If those are grouping well broadheads and field points I wouldn't change a thing. When I shot A/C/C's my FOC was right where you are at and they flew great. When you need arrows in the future I would look at going to a 340 spine to see if you can shrink those long range groups. With that you will need to retune for the spine because your centershot will slightly change with a new spine.

    I wouldn't go to a 125 grain head with your current set up it would weaken your spine even more. I would leave it alone

    Ontarget, what program do you use if you dont mind me asking?

    EDIT: The program you use to determine correct spine of specific brand arrows.

    Not trying to step on any toes here but if your wanting to calculate the FOC (front of center ballance) of your arrow setup, Google "arrow FOC". There will be many sites that will tell you how to do the calculations along with recomended FOC for field tips and broadheads. Hope this helps...........

    Sorry I didn't get back with you sooner but was in Vegas in the 3 day archery shoot this last weekend.

    I use the TAP Program. There spine selection has been very accurate for me and they are extremely user friendly
