Surewood douglas fir shafts rock my world. Love making mulefat shafts, using hill cane, but those douglas firs shoot real good.
Like you, I find that an extra half inch on shafting matters ( I weigh my Zwickies, and find that they are 133 grains starting out, and that sort of bothers me, given that I can spend a lot of time making matching arrows ).
But then again, can I "shoot the difference?"
Any case, nice shafts....
