Just got a 174 P Virus tonight. I've been a big Amp fan since they came out, but since I use them as fairway drivers they fly stable until quite beat. I was basically hoping for a seasoned Amp out of the box. There was some flashing that I had to remove with a towel because US discs can be unnaturally HSS with even a little ridge at the bottom. My initial impression is that it flies like a faster/longer newish Polaris LS. Compared to the Amp it seems faster and has a little less glide. It also tended to "click" into it's flight phases more deliberately, where the Amp has smoother transitions and a curvier flight. Definitely interesting and fun to throw and I will be adding more once I've tested it more.
