Yes, another recommendation for Douglas Fir from Surewood Shafts here.
Have made and shot many many dozen Douglas Fir arrows over the years, with not a single issue.
Minimal if any straightening necessary, they stay straight, more durable than cedar, and they have good weight, and they finish nicely. Douglas Fir makes a good looking great shooting arrow that no doubt shoots way better than I can 😁
I've shot 10" tail tapered, full "Rat tail" tapered, and parallel, and honestly, I guess I'm just not a good enough shot to tell the difference. They all shot great for me. So I just shoot them all parallel now, and we get along famously.
I've used wood shafts exclusivly in my 55lb, 65lb and 75lb longbows (never ever used anything else actually 😉) and at least 90% of those have been Douglas Fir from Surewood.
The only reason I'm not using Douglas Fir in my 75lb'er at the moment, is the difficulty getting Doug Fir shafts with a 105-110# spine. Using Forester Wood Shafts Red Balau in the 75lb'er. That stuff is extremely strong durable wood, but it's very heavy.
Might be a tad too heavy in a mid 40's bow for some.
But I don't reckon you'll be disappointed with Douglas Fir shafts, nor will you be disappointed dealing the good people at Surewood Shafts.
Best
