MA111 55@28 60"bow. I can shoot 2016's thru 2117's with great results. 45 gr inserts and 165 Zwickeys upfront. Shooting 3 fletch 4"feathers.

what does a 2116 and 2117 spine out at?

A 2016 would be about a .450 spine I would guess. A 2117 spines out at .400 I do know that the 2016 is just a guess though

Oh and Daniel have you tried using a drill bit inside the arrow to see if you can "punch the inserts out the end of the shaft. Warning do this outside and not facing any cars or windows as the inserts and drill bit when they come out are moving at very high speed. It does ruin the current inserts but usually not the arrows.
