I have a dozen 3555 Gold Tips that shot great in my bow w/ target points. But they shot about 5" low at 20 yds. with 85 gr. Thunderheads. I could not put enough helical or straight angle in the fletching or it would interfere with my rest. So I ended up shooting 2312's the last few years. Well, I just ordered a TR drop away rest and want to try again to get the higher speed with the lighter Gold Tips. I figure I can fletch them full helical (w/ drop away rest) and hopefully get them to group with my field points. Does this seem like it would work? What's the best way to install inserts in the Gold Tips? I remember having some of the Easton inserts pull out when removing broad heads from a target.
