True story, the first year I tried shooting trad, I of course shot cedars. I broke them on stumps, rocks, target frames, glancing shots on saplings, you name it. Looking for a stronger shaft I tried maples from Silent Pond and them things seemed about bullet proof but at my 32" draw weighed about 800 grains and past 20 yards really dropped. Shot them for about two or three seasons then tried cedars again and suddenly my cedars were just as strong as my maples for some reason. Shot all year and maybe broke one arrow. I couldn't figure it out. Plus, after shooting the heavy maples the cedars looked like they were wicked fast in comparison and of course cedar stays straight better than about anything I've tried to date especially the hardwoods like maple, ash and hickory. So
So what was the deal with the cedars being bad the first time and great the second? Eventually I figured it out... I was simply hitting the target instead of trees, rocks etc. like I did my first year. As for weight, at my long draw cedar gives me about exactly the weight I want but I understand that people with draws 28 and under often come up lighter than they want.
This year I'm trying some Douglas Fir and they are real nice but a lot heavier than cedar. Still lighter than maple so maybe they'll be reasonably fast AND hit like a freight train eh?
As for the German Pine shafts, I have no idea. My guess would be something like chundoo or norway pine but that's only a guess. The one time I tried chundoo I was VERY disappointed. Crooked as heck and grain runout all over the place but maybe I got a bad batch.
Let us know what you think if you try them out.
