These are premium pine shafts, spine and weight match. I am actually quite proud of this set as I have managed to weight match these withing one grain if you think there is 15.4 grain in 1 gram it's a good going. Don't waste your time and money with cheap arrows These are spined 50# After trial and errors I found that this level of Slight helical on the fletching they do spin nicely as it leaves the bow. Self nock on these clips on nicely unlike cheap self nocks you can find on the market.
