You will need the 500s and ya may need a bit more weight up front than 125. Ya fail to mention how far the bow is cut past ceneter and if it a high performance bow or not. Shawn

agree w ith Shawn. I shoot 55 @27 and I need
almost 300gr up front on 28" arrows( 100 gr brass insert and 200 gr point)to get the 500 to tune.

I do not want to sound like a pain but the key is the length of the arrow he will have in the bow.

I shoot the 500 size  bemen hunter arrow that are cut to 29 1/2 in length, my bow being used is 50 lb at 28 checkmate firebird, I draw 29 inch. I am using the 125 gr points, with no adder weight of any type. The feathers are 3, 5.5 inch bananna cut fletch. I seem to get very good arrow flight.

So tell me how you identify the need for more weight up front. what do you see as poor arrow flight etc.

"Can someone tell me the advantages of carbon besides durability?"

Chub... typically carbon shafts are smaller in diameter than aluminum which can benefit penetration on game.

They can be "front loaded" when tuning which helps flight characteristics. That and carbon's inherent stiffness also helps limit "noodling" of the arrow on hard impacts (a penetration limiter).

If the bow is cut well past center you can get away with a wider spine of arrows. Bill, try shooting them bareshaft and see where they hit. If they hit left of your aiming point they are too stiff, I believe, you would need closer to 175 up front for perfect flight. I am not trying to be critical here but I have seen what people call perfect arrow flight and more than half the time the arrows fly terrible. Shawn

It has been my experience (very limited with carbon) that the carbons recover very quickly when they leave the bow.  I have been bare shaft testing for many years and am picky about arrow flight.  The quick recovery is an advantage in my opinion at the close range most hunting shots are taken.  I have shot aluminum since the 70's and the new carbons have converted me.
