I am looking for some sugestions on arrow set ups for the upcoming year in 3D competition. My bow is set up for hunting right now and I am going to change the poundage to 60#. It is currently at 66#. I shot a Switchback and use Gold Tip XT Hunters 5575 at 29 inch with 100 grain tips. My question is this, what is the best arrow set up to close in my group for better results in the 3D meets? My draw length is 29in and I have room to cut an extra inch off the shafts if need be. On a good day I can group about 3 to 4 inch diameter at 30 yards.
