...2117 on paper "should be" close.
Depends on several things , like cut to center, shooting style etc...Agree with those above. 2117 "should be" close.
If the shelf is built out , slower/heavier string/silencers...you might get a 2018 to go with that nose weight and insert weight ?
You can be two types of people....cut all your arrows at one length and go from there ...or play with the length in the tune process. I would add a couple 2018's in on the "to try" testing block. I just LOVE 2018's and they fly well from a wide range of weights & the 5/16" dia and thick wall make for a very TOUGH shaft .
other's might be 2216-2213 if that dia. is an acceptable perimeter
