I have tried that in the past, Shakes...with poor results...when I cut the square roughouts from the stock the hickory bent like I had cut them out of hoola hoops and would NOT stay straight more than a few minutes...and that was very dry, well seasoned wood with low moisture content.
They are a step UP in my mind....they are 50 times more durable...weigh more...stay straight (the ones I have gotten from Troy Breeding do- I have not tried any from Alleghany but suspect they are good shafts also).
The only downside to them is when they DO break, which isnt often, they don't have that pretty smell...but hey, I don't LIKE breaking wood arrows.
I have shot 7 armadillos with ONE of my Troy Breeding shafts...anyone who has ever shot an armadillo will tell you they are tough on arrows.
Wash it off, resharpen, put it back in the quiver and she's ready for dilla.
