Hi Gang,

I'm trying to select the correct weight of cedar shafts for my new setup. I am shooting a Browning Wasp 42#@28. My draw length is 27-27.5. I'd like to use a 30-inch shaft if possible, with a 190-200 grain head. I looked at multiple spine selection charts. The general consensus based on the charts was 60-65 spine. However, when I called and spoke with a rep from Three Rivers, his recommendation was 50-55. He also advised that their company spine chart was on the heavier side. I am torn on this. Any advice or recommendations to break the stalemate would be appreciated.

Best,

Ed

Because a 30" shaft is ten pounds spine weaker than a 28" one, of which all wood shafts are spined for. And your use of 190-200 grain points weakens it another 10 pounds spine.

Why do you want to use such a long arrow?

What Kelly said. Long arrow, heavy point make the shaft weaker. Part of what I call the "5# rule".

55-60#.  Does Three Rivers still sell bare "try shafts" of three different spines?  Try 50-55, 55-60 and 60-65#.

I agree with Kelly.  If you went to keep your arrows that long and points that heavy, you're going to need the heavier spine.
