Douglas fir all the way for me. I did get ahold of some Hemloc shafts from Surewood and they seem to have the same characteristics as douglas fir, just not the higher weight. I have made some up, but have not shot any. I plan on donating them to the PBS banquet in Cincinnati this March.
BUT, like I mentioned, I only shoot douglas fir. There are a few suppliers that are sponsors here on TG that sell either the raw shafts or completed arrows.
A few years ago, I did a pretty extensive research on the best arrow shaft for ME, and hands down, the douglas fir shafts that came from Surewood beat out all the others. YMMV
