I got a PA 4 in 350G plastic for Christmas a few months ago, and I'm loving it so far.  I use it primarily for approach shots, though it also works well for putting.  For drives and approach shots, it has just a touch of turn and a touch of fade, true to the listed flight numbers.  The turn and fade combine for a shot that lands exactly on the line you originally put it on.  This disc is very neutral and can accommodate a variety of shots from hyzer flip to S curve to anhyzer.  Being a putter, this disc doesn't skip much, and it sits down pretty well when it lands.

The 350G plastic gives an outstanding grip, but doesn't seem super durable so far.  After only a few months, it already has some sizable gashes in it, and I wouldn't say that it's hit a tree with all that much velocity yet in its short life.

Also worth noting: the PA 4 is on the shallower side for a putter.  My wife, who struggles to grip discs with deep rims, prefers the PA 4 for putter drives and approaches.

The PA4 is an understable putter from Prodigy discs. My first thought on this disc relates to the feel in hand. It was different feeling, almost kind of bulky feeling. It wasn't uncomfortable, but it did take some getting used to, but once I did, I started hitting putts in the circle. It has a super straight flight when putting and decent glide. I was not a fan of this putter for throwing, it just wanted to turn for me. I like putters with a bit more stability for throwing. Check out the PA4 if you are looking for an understable putter.
