I'm using cedar shafts. And yep they are tapered.

Man I'mnot really up to date on the technical stuff. I just told the guy I was buying the arrows from what weight bow I was pulling and I asked him to leave the arrows a couple of inches long so I could make adjustments. I guess I just got lucky, only had to make one adjustment to get them grouping with field tips.

I just ordered 500 Ramin dowels from Altas. I plan to make a spine tester and get a grain scale. These dang cedar arrows are just too expensive and too fragile.
