I don't doubt the superior edge holding of the regular grizzly stick broad head over the overkill series, I not sure it merits consideration for hunting purposes. I say that based on a recent Ranch Fairy video where he discussed and showed the difference between 2 different tuffheads he had shot through pigs and 2 that hadn't been shot and were hunting sharp. I know he takes his sharpening seriously and there was a striking difference. To me that illustrates the point that resharpening/touching up will be a necessary step before every hunt.
I also am under the impression that the softer steel of the overkills will take an edge easier but that may just be my own misguided notion.
Also I have the 125gr maasai overkills that I'll be shooting this year. If you go with theaasai's I recommend the staysharp "C" series sharpener for keeping them sharp also. It made taking mine from sharp to scary sharp a pain free and easy process.
