I have shot both the 3 blade and 2 blade VPA's.  Both are great heads but do need sharpening.  There was a thread on one of the other forums where the VPA rep explained that they could not sell these for the price they do if they had to finish off the heads to razor sharpness.  I have taken deer and pigs with both. Both have been good I just like a two blade better on the end of my arrow.

I shoot 175, 200 and 250 so I guess I must like them...hard to find a better two blade
