I shoot cedar for just about everything. Generally I mount 125 Zwickie or 135 grain Magnus heads and use 5" shield cut feathers on 29" arrows. My Hills like arrows spined for their stated draw weights @ 28". (I draw less than 28".)
I bought a dozen Douglas Fir arrows not long ago but have not shot them much in all this hot weather. I think I will like them also but have not yet used them enough to really know much about them.
As for breakage, cedar may not be as strong as some other woods, but it is not a pansy wood, either. I have bounced many of them off trees, rocks, etc. with no problems. But when they do break, you sure get a fragrant shower of splinters.
