Someone please run these numbers for me.I'm want a little higher foc with my current arrows,heres what they will consist of if able.cx maxima's 350 29" lenght,dw 64lbs,from a bowtech commander,arrows are also 29" tipped with 125 muzzies and a 50 gr brass inserts.What I need to know is,total arrow weight,foc,and will they still be spined correctly.They are set up just like this now,without the brass inserts.OH no wraps only 2" blazers.

What nock and what vanes?

If you are going with Blazers and a 10 gr nock.

The arrow should be around 439gr's, FOC 17.3% and optium spine.

RUSSEL; they come with the buldog nock and collar,are you sure about the total weight I just looked on my arrow and we weighed it at 428grns with just the 125grn point,we wrote it on one of the flecthes,I forgot about until I looked at the nock.I really want to make sure I'm not going to be underspined by adding 50 grns of weight to the tip.
