OK AA came up with a finished weight of 371gr's using the 2" Blazers the FOC is 13.6 but the spine is all the way over into the red on the stiff side.

Even with a 125 head it is still showing as too stiff.

Now with the lenght cut to 29" 100gr head it is showing slightly stiff, 388gr's with a FOC of 12.9

Now if you want to get the FOC up there go with a 200 gr head cut the arrow at 28" for a total weight of 479gr and a FOC of 21.1 and slightly stiff on the spine, I would prefer to be slightly stiff than slightly weak when it comes to spine.
