To me these heads perform equaly in the field, so it is a matter of time versus money. Would you rather have the 2 hours it will take to put a proper bevel on the 6 pack of grizzlys by hand or the extra 40 dollers it will cost to buy 6 abowyers. Once you have the initial sharpening of the grizzlys done they resharpen about the same as the abowyers. Figure in the personal satisfaction you get out of preparing your broadheads and you have your answer. Also note, that if you do not have a good quality file, grinder or sander necessary to put the initial edge on the grizzly,the cost difference is less.
