Sanding any nocks, let alone those tiny ones gives me the heebeejeebees. I did some digging around, so here's some info for anyone else who was wondering
First off, the nocks on these arrows are the Easton super nocks. The 3D super nocks throat opening is .102" and it looks like the normal super nocks have the same (?)
The Bohning classic nocks I put on all my woodies have a throat opening of .118". The Bohning signature nocks for carbons have an opening of .112", which should be just the ticket with a 12 strand B50 flemish twist with .020 Polygrip serving. If I can manage a trip up to the new Cabelas this weekend I'll let you know
