Have you thought about shortening the arrow a little to up FOC? It will probably only give you a small percentage change but will raise the FOC. Making the arrow 30" will give you about 3/4 of a percent increase if I have your arrow numbers close in Ontarget.
Also, anything that is done to lighten up the nock end will increase FOC.
I use OT2 also and if I understand it correctly I thought the shaft length is just the shaft not counting the nock or the insert/point. That is why I made the shaft itself 30". Adding the point and the nock made it longer. Actually I am about as high at FOC as I am wanting to go with this particular arrow.I may experiment with some heavy inserts so that I can use a different point/broadhead ( I have6 more to experiment with).
