I' m considering these two heads. I know you haven' t yet had an opportunity to fling the 4 blade stinger since it' s not out yet

, but that' s the one I' m considering. For purposes of this discussion, let' s assume it performs as well as the 2 blade...
I like the fact that the montec can be easily resharpened on a flat stone (which I have). I think the blades would be easier/cheaper to maintain than the stingers (which would require a different sharpening apparatus or cash to purchase replacement blades).
In your experience, assuming whitetails and 60#s + of ke, is one superior over the other in flight characteristics, ease of tuning or penetration?
Which would you pick and why?
