Over the past decade the mechanical has made the main stage and some like and some dislike. I have shot quite a few brands and the out come 80% was good with a downed harvest. I have been on the 20% side at the wrong time too, ether open before it reached it target or didn't open at all. I know shoot Slick Trick Mag 100g, the out come has been fantastic and they characteristics are very similar to my field tips. I'v downed Elk to big mules over the last few years with that set up. To answer your question I like the Grim Riper 100g as they have a set cap and never had one open up in flight. The flight was also field tip tight. I'm gong to stay with Slick Trick Mag as I alway no that they will deliver, I may not but they will.
