The A2 is the overstable upshot disc you want. Tends to spike and not skip/roll away, you can really park shots with it. Also a more comfortable shape for forehands than most putters or mids.
Love the way the plastic feels in my hand, especially for forehand flex shots in the woods. This model and the "soft" version Austin Hannum signature series are amazing approach discs. I love all the new SIgnature Series discs and initially, I wasn't excited about them. Go put one of these in your bag...you will thank me later!
The A2 is the best overstable putter in the game.
