Tires? Did someone say tires?
See my review of the Z1SS, RE11, and more at

My question for you is, what exactly is your objective with new tires? Maximize dry grip? Wet grip? Feedback? Tire life? Cost? You can't get everything, so list those in your order of priority, and I'll make you a recommendation.
I go through a lot of tires...
