RE: Recurve?
I now use a compound but tourny & bowhunted with recurves for many years. Shot black bear, elk & many deer plus a couple wild hogs.
I preferred the Aluminum back then thou i did shoot a few animals with wood also. I shot 60 & 63 pound recurves for hunting & used a 2018s on Deer & On the wild hogs, Elk & Bears used 2216s 2 29" draw. The heavy shaft gives you the complete penetration & most of your shots are 25 yards & under. i never worry about shooting a slow arrow.
I still use heavy shafts for bigger animals with the compound.
I have a Buffalo hunt set up for next fall & will be shooting a 60 pound compound with a 2216 shaft & a 3 blade Rocky Mountain razor. heavy shaft will give me the penetration I need. If you just plan on deer hunting you could shoot a lighter shaft but I still prefer the heavy for penetration. good luck & enjoy.
