My understanding is; most who prefer mechanicals is due to the BH acting like their field points vs Fixed heads, is this not the case?
That is the very reason I shoot them, I have shot fixed blades in the past, but for the very reasons given by BOWFANATIC I prefer mechs. Another fact that BOWFANATIC brought out is true
Are there stories of mishaps with mech heads? Sure! Are there stories of mishaps with fixed blades?? Darn straight!
To each there own, there are advantages and disadvantages to both mechs and fixed blades, I will take the increased consistant accuracy of a mech over a fixed and not take sharply angled shots.
