Just changed to GYF1 A2. Compared to my previous rft Pirelli P Zero, they are certainly much softer and takes the edge out of rft. Braking is stronger and so far very happy with it. Defininately a good recommendation especially at that price point. In fact in a recent test by evo magazine, it came number three after CSC 3 and Hankook.
I will change my rear tyres once those Pirellis have worn out. Now I am hunting for puncture kits. Lol!
