WITH A MODERN COMPOUND BOW, MECHANICAL BROADHEADS ARE SUPERIOR TO FIXED BLADE BROADHEAD. FIRST OVIOUS ADVANTAGE IS ACCURACY. SECONDLY, THE MECHANICALS HAVE TREMENDOUS CUTTING DIAMETERS. YOU COULDN'T SHOOT A FIXED BLADE BROADHEAD WITHMATCHING DIAMETERS. THIRD ADVANTAGE IS SAFETY. MECHSBLADES ARE NOT EXPOSED TO YOU LIKE FIXED. I ACTUALLY CUT A STRING WITH A FIXED WHEN I WAS YOUNGER. THE BIGGEST PUBLICIZED "ADVANTAGE" FIXED HAVE ISPENETRATION. THERE AGAIN MODERN BOWS ELIMINATED THIS AS A FACTOR. ITS CALLED EXCESSIVE KINETIC ENERGY. I HAVE KILLED 70 OR 80 DEER WITH MECHS. 98% WERE COMPLETE PASS THRU. I HAVE BROKEN JUST ABOUT EVERY BONE ON A DEER YOU CAN THINK OF.THE GREATEST DISPLAY ON PENETRATION I HAD WAS APESKY DOE WHO WOULDN'T STICK HER BODY IN HARMS WAY. THE SHOT WAS A 18 YDS. I PUT IT IN HER EAR AND IT PASSED THROUGH HER CHEEK. ARROW WAS BURIED 10 YARDSBEYOND TARGET.
