Since I bag a Harp with almost identical flight numbers, I had my doubts about the A2. However, due to the Harp's mold, or it being more beat in, I was looking for something a bit more O/S for shorter BH flex lines, or shorter distance BH high hyzer throws. I also wanted an approach disc for some touch FH shots, and the Harp was not a FH disc for me (with its deeper rim, it's just not my preference).
The A2 out-of-box is showing true to its flight numbers, and has more of a mid-range feel to the mold. I love throwing it FH on shorter distance throws with its shallower rim, and flat top surface. This disc throws fast as hell for a 4 speed, not scared to rip it flat off the tee BH, or a little anhyzer if I need it to make up a large chunk of distance straight until it fades hard to the left at the end. Giving it 4 out 5 because it's everything I was looking for, but I haven't gave it enough play to say it's perfect (I still bag the Harp). The A2 has found a home in my bag as well though, and I'm not looking to take it out anytime soon.
