I'm not knocking any of the suppliers, but as expensive as so called matched shafts are ( and some are only spine matched, not weight matched ), I'll stick with dowels. You can't beat the price.
I might have considered matched shafts in the past if I wanted to make a set of arrows quickly. but after the HUGE price increase, I'll never buy a dowel with the title of arrow shaft, I'll just buy regular dowels and I'LL be the one that decides if they deserve the title of arrow shaft or not.
