I sincerely like the doug fir real well. It is tough , stays straight, looks great when stained and sealed and basically is a great wood for arrows.
I also shoot and like the Hildebrand spruce as well. Tough as nails, holds their alignmenet real well, stains almost exactly like doug fir, and are exactly the right weight I am looking for when I call and get them from Neil.
Here is my expierence with the shafts, which isn't nearly as much as some but has some merit also. I am shooting the doug fir in 75-85 spine and they are coming out of a 60 pound recurve like a missle. They hit real hard and make for a dynamite combo. I am also shooting some 75-80 spine spruce outta that same recurve.
I have yet to break a spruce shaft. I have broken 4 fir shafts and no spruce shafts. Now, no more samples or shots that I have of them both it may be a little biased but I have shot the spruce into the same stuff I shot the fir and didn't have a problem.
Now you have got to understand, I am not shooting the premiuim shafts in the fir as I am in the spruce and they do have a little grain runout in them, so this is probably the difference. A couple more dollars on ordering day and this wouldn't happen and I am certain of that.
The bottom line is that both are excellent choices and both make dandy arrows that are strong, stay straight, and both are found in a large variety of weights. And both Surewood and Hildebrand are top notch people bro. I say get a dozen of each in your spine and weight range, finish them, and you are going to have a real hard time telling the difference in their performance.
God Bless
