I shoot 1916 (27.5" lg) out of a 45# recurve and with a 125 gr point, the weight is about 440 gns if my memory serves me right. I just got a 42# longbow and the 1916 seemed stiff, so I'm going to try some 1816's tonight. Bill is right, I have also shot 2114 out of 50-55# recurves and they flew well. They may be a tad stiff for 46#, you can use them with a heavier head. I prefer to stick with xx16 or heavier wall. IMO they are a little tougher than thinner walled and slightly heavier.
