Slick Trick viper tricks for me. My setup is 65lbs firing a 430g arrow 275fps, not a hot rod by any means, but I still get mostly passthroughs with them and good blood trails. Two years ago my 125g viper trick penetrated my bear from the throat and out the back of the ham for an end to end passthrough. It only ran 20yds.
For deer I’d use anything that was sharp and flew well with a good reputation. For elk I would never use an expandable just due to the fact that you lose penetration and the majority of them have flimsy blades. Yes some guys are very successful with them, but I see no reason to take that chance on the sole thing that actually kills the animal.
