I have one shot at this one so hoping to get some feedback here. I am looking for arrows for my 48#@29 cut to center longbow. I want to keep the tip weight at  200 to 225 and the arrow length at 29.5 (I draw 29). I am trying to decide if the axis 500's or 600's would be the better fit. Any help would be greatly appreciated.

What are the limbs made of?

Its a Brack Non Typical....no carbon, no foam core limbs...and it is actually cut 3/16 past center

my quest likes heavier spined arrows.....I assume the NT would be the same

500 possibly a 400. 600s will be weak+

I agree with David.  I think you are right on the edge.  Being a longbow, I'd lean to the 500s.
