Hi Matt
I could be persuaded to part with some of my Carbon Heritage 150 shafts.
If you have a look on my Archery Bits and Bobs to trade on the swaps page and have anything on my wanted list we might be in business.
The black stuff on the shafts is just the ink from a 3D bear.
I have arrows fletched with Rain Vane's, feathers or shafts only.
I have both new and used but all the used shafts are all are still in very good condition ,As soon as any of my Carbons get damaged I usually ether chuck them out straight away( Standard practise with Carbon) or use them for something else ,Tent poles ,Tracking Stick’s est. est.
Reused Carbon 150 shaft as a Tracking stick, I also saved a ton o weight replacing my aluminium tent poles with old carbon shafts.
Anyhoo.
Later Bro
