I'm planning on using Magnus Stinger 4 blades. Used them for the first time this past year and got wicked penetration and very quick kills on a medium sized doe and spike. Both fell within 50 yards. I actually made a very poor shot on the doe (high and back) but she only ran about 20 yards stopped, looking around and tipped over. I'm tempted to give the Rage 2 blades a try but they are $10-15 more expensive then the Stingers and I can't imagine them killing any faster - some of those Rage holes are pretty dang impressive though
