RE: Mechanicals heads?
I use mechanicals,and I can tune a bow.I am not a fan of the Rage heads(for me),there,I said it.[8D]I used them last year and it seemed to me that they were extremely noisy in flight,and not quite as forgiving as my Steelheads.I love the Rocket Steelheads that are only a 1 1/8" cut and most deer I have shot with them were down within 30 yards.
The original poster didn't like the idea of checking or worrying about his head opening or whatever other reasons.What I don't like about fixed heads is their unpredictabilty when I lean out around a treeand torque the grip on my bow or I have a pretty good cross wind.Fixed heads do not react like field tips,regardless of how they tuned,especially when using lighter arrows.A quality expandable will react almost the same as a field tip.
Bottom line is,I have more confidence in a quality MATCHED mechanical.
