Well,you've done what I would have suggested to do already.My RM titanium 100's were hitting 2" lower than my field tips.My nock was set at 1/4" high.I moved it down to 1/8" high,and now they are hitting the same.I have never found a fixed blade broadhead that hits like field tips.I have heard stories,but have yet to see it.Honestly I would just move the sight.Even that little bit shouldn't cause the field tips to fly over the target or anything.Hope I helped.
