Josh, is that 30.5 including the broadhead? Also the weakening spine theory is the main reason why I went with such a heavier grn per inch, 12.7. Now I'm wondering if it is too much?

Does anyone know approx. what kind of speed these arrows will produce out of my set up?

I never really thought about it (weight) when I was shooting the aluminum arrows, I would like to think the carbons would be faster? my aluminum arrows were Easton GameGetter II 2219 everything else is the same.

Thanks
