If penetration is your biggest concern than obviously a quality two blade head will theoretically do the best job in that catagory all things being equal.

But once a guy lets any arrow go strange things can happen. I was shooting a rig that produced over 70 lbs. of KE last year when a nice buck walked under my stand. When the buck stood broadside at twenty yards the two blade head hit the shoulder area acheived good penetration but I didn' t get a complete pass through (the arrow penetrated both sides but stayed in the deer until the arrow broke). I figured I hit the shoulder bone on one side or the other...NOT! I hit one rib and the rest was muscle and tissue. Same setup except with a mechanical two blade (with a larger cutting area) shot completely through a bigger bodied buck entering the back of the rib cage and exited out the front of the deer' s chest as he was quartering away, go figure. Neither deer went 50 yards. I use these two examples to illustrate the intangibles that can happen in a hunting situation. Sometimes the obvious isn' t so obvious.

I don' t have any experience with the slick tricks or the razor caps so perhaps I should be eliminated from your survey. That said I have shot elk with 125 grain Muzzy 3 blade, a Rocky Mountain 125 grain titanium, and a 125 grain Montec G5. The Montec was the only one that got a complete passthrough. Truthfully that was more a matter of shot location than anything else however. For what it' s worth, the Montec was as good as new afterward.

I' m hoping to hunt elk this fall again. I will have the Montec G5 on the end of my arrows.
