I've been a Slick Trick/Viper Trick fan but used Magnus Stinger and Buzzcut this past season with good luck on elk and deer. The problem is it's not as simple to swap out blades on the Magnus but I returned three damaged Magnus broadheads which had killed two bucks and one cow elk. They replaced them all no questions asked. They did the job but were kind of one and done. I've not had that damage experience with the Killer Bee.
I also would not consider the Viper Trick a true cut on contact. It is very pointy, but not truly sharp. But, I also don’t think it matters much for compound shooters. Some of the guys that shoot piles of elk here use ST Viper Trick.
The Grim Reaper micro hades is a replaceable blade, mid price head, that actually does have a sharpened point. Lots of people recommend those as well.
Watch the Lusk reviews of both. Both great heads that will kill elk.
