Ok today I replaced my 145-175 field tips with 125 on my 2018's xx75 cuy to 30" and shot them out of a 58" Grizzly @ 42# 29" draw and they flew great! All I see is feathers and nocks no shaft fishtailing! They Shot equally well out of a 45# Grizzly dogleg 62", as well as 46# Ancient Spirit recurve, I got whipping out of a 37# Wing Gull 64" I also swapped my 175 field pts out of some Gold Tip Trads "My standard arrow for most bows" with 125 and they flew great...super straight. Some 1916 and 1918 are on e bay right now would the 1916 be best for the lighter Gull? How about the 1918 instead of the 2018? Or if I get the 1918 what tip would bring them close to the 2018 performance? Thanks
