I just got done test driving a PTFV last week. It was indeed a sweet shooter. The Asbell grip seems super easy to just point at the target with little effort. My bow hand just naturally aims at the spot I'm looking at.
That being said, I placed an order for a PAX because I feel like MAYBE a little more weight in the riser may quiet/stabilize the bow. Of course this is just conjecture. I have heard many guys say that all the Widow models shoot about the same for them.
Can't go wrong with a Widow. If they weren't a great bow, they would not have such a following.
