Replaced the well known and trusted BT 010s
Pros:
Much much much much stickier leading to huge buckets of corner confidence
Different profile leading to much quicker turn-in when counter-steering the above corners

Identical performance in the wet (i.e. OK but not brilliant - though much better than 020s which were pants in the wet

)
Cons:
Due to the softer compound they wear out quicker than a badgers arse and a rear is only good for 3K (front will stretch to 4K)
I have 3.5K on mine at the moment and I almost dont need the stand cos my bike will stand up due to the tyres being so squared off!

overall:
fekkin brilliant and highly recommended! love 'em to bits for road use/very occasional trackday
