I just went darkside about a week ago, General Altimax 205/60/16. For the most part I can't tell a differance. There is a very small differance when taking off say from a stop sign, you are turning left or right at a slow speed, during the last few feet of the turn the bike wants to stand straight up. if ya had never ridden the bike you wouldn't notice, you'd think it's just the way the bike rides. It wants to stand up straight more than before, (the counter steer) after half a tank of fuel you'll be accustomed to the new ride. I currently have 30psi rear and 40psi front, D404. These two tires are a perfect combination, thanks to advice from this site. It feels like it ain't goin nowhere but forward, very surefooted now. I'll post pic's.
