I switched to VPA 100 gr. 3 blades this year, and I'm eager to try them on elk in a little over a month. I shot them out to 60 yards a few days ago with my Bowtech Experience set at 68 lbs, and I was getting groups that were five inches or less at 60. They did shoot a couple of inches to the left of my field points, but that was an easy adjustment to make on my sight. They are also a very strong broadhead. I buried one of them in the dirt because I moved my pins too far on one of the shots, and it came out completely unscathed. I also like that they are easily resharpened and reused so I don't have to keep track of replacement blades and such. I haven't put them to the ultimate test yet, but from what I've seen thus far, they should do great. I have also used the 100 gr. Muzzy three blades before, and they pass through muleys like their isn't anything there, so I think you would be fine with them on elk as well, but I liked the all-steel construction of the VPAs for elk because of their larger bone structure. I think the bottom line, as has already been mentioned, is get a reputable broadhead that flies well in your setup, place it where it needs to be, and you'll be fine. Hope that helps. Good luck.
