Which tyre for zx6r 06

Hey guys
i am seriously a noob when it comes to tyres...
i have the original bridgstones on my zx6r 06 model and they are going on 4 years old now,
they have a puncture repair and only have around 2mm of tread
i believe i should get new tyres? i was told that the original tyres where quite hard anyway.
seeing this is my first sports bike i really wanna start off with some nice grippy reliable tyres.
please point me in the right direction!!
