I used the German Pine recently for practice arrows for my teenage daughter, they worked out fine for that purpose. the weight range within the dozen was a little broad, and they were not the straightest shafts I've ever seen but they straightened out pretty easy with a little compression. the grain run-out was not any worse than most cedar. they would probably work out OK as hunting arrows if you picked through a bunch and used the best for hunting and the rest for stumping.
the best shafts I have gotten in the last few years were sitka spruce from Hildebrand, every shaft was pretty much perfect and the weight only varied about 20 grains over a hundred. they make an arrow a little lighter than I would like for hunting, but now that I've gotten into gasket lacquer I'm just finding out that you can add some weight in a hurry with more coats.
I am still using PO cedars that I made years ago for my hunting arrows, have not tried Surewoods yet but from all the good things that are being said I will be giving them a try
