I just got my new grain scale and went through some arrows I made. I am sorting them, relighting my pipe, sipping on Earl Grey tea, I should have used something to denote the batch, so I am grouping them by weight. Perhaps go with varied thread colors, i like to serve the first little bit of the lead end of the feathers. there is something calming about wood arrow building and fixing during the off season. Fletcher, thanks for the info. Surewoods and Doug Firs are on my to do list.
