been away for a while- tyres

[SevenR]

Hello all.
I've been away from riding for several years now. My brother has offered me the use of his monster ZX10 which I did a track day on the other week. It was amazing and re-lighted my love of 2 wheels like I wasn't expecting.
Tyres on it are track day affairs, so I'm wanting to put a set of road tyres on it.
What are considered to be the best tyres these days for the big bikes?

Cheers.
