Just chipping in with my experience of the Eagle F1's -
Had ContiSport 5's on when I bought the car (Feb), ran them for about 2 months until I got a puncture in 1 of my fronts and ended up replacing both front's with F1's.
Both seem to have fantastic wet and dry grip, the F1's seem a little more "comfortable" on the road, I don't feel like I notice the rough road surface quite as much as the Contis.
I've never really reached the limit of either tyre, and rate both very highly. I picked the F1's up for £69 per tyre from Tyreleader - DOT marked late 2014.
Agree with this, feels like they have a softer sidewall compared to the contintentals, which is very good for commuting, and doesn't really make much difference on track either
