RE: Arrow weight question?
Actually the 2016 if absolutely off the charts weak. The 2216 is even weak on the spine graph in my program....it shows yellow green weak.
a better match based on your setup appears to be a 2315. Shows perfect spine. Also the same weight as the 2216.
As far as KE goes it won't change unless you change the powerstroke (draw length) or the poundage of the draw weight. This debate has been pounded to death so I won't go into the physics of why, a quick search here should find all you ever wanted to know about the topic.
The performance I would have to guess would be night and day with how underspined you currently are. Shooting a propererly spined arrow will be FAR more forgiving for accuracy and durability.
Happy Shooting!
