You cant cut them off?
Tonkin cane and 225 grain Tuffheads, are flying sweet for me.
Draw length (arrow length) bow weight, centershot amount and the mentioned head weight all come into play and of course the spine of the shafts. As in any shaft material……all are not equal.
I use the same old, same old cedar arrow taper tool on my tonkin canes cut to length.
God bless
