Black10R, well spotted! I was waiting for someone to suss the blue circles out!!!! I was gonna Photoshop them out, but left them there for fun. I nearly gave up and was about to post the answer
Anyway... Yes the tyres are Conti Sport Attacks (I did say this in my original post!). They have only a couple of hundred miles on them, so you can still just about make out the 'Conti Attack' imprint. The blue circles are from the film on the lens of the camera. The sun was low and I was facing it when I took the shot, which caused this.
Thanks for the replies everyone. I don't feel so bad about the strips now! I feel more content taking the piss out of my m8's rear strips on his new 10R! Until recently, I never really looked at other peoples tyres. At the recent bike meet, MOST of the bikes had strips on the rear, never mind the front. Still, it appears that it is no real guage on the rider overall, just how far they lean into a corner or roundabout.
