I love the conts and usually either buy those or f1s but i have leaned more towards the contis recently due to the availability problems of the old f1 assymetrics, tbh those are my first choice tyres every time and have not tried any of the new offerings from conti or goodyear but no doubt both will be brilliant, id personally go for the cheapest even if there was only £1 in it !
Although just a thought since you do a few track days what about the mitch super sports they are meant to be absolutley superb and wear brilliant too, ( fair enough a little expensive )
When i change it will be between the above 3 !
