What track day tyre is the quietest on road?

[Steve]

When weather warms up I swap from winters to my track day tyres at present NS2Rs.
On track perfect, on road again performance for cost is excellent.
Where they fall down for me (mx5 folding hardtop) is the terrible road noise!
Fine with the top down but terrible with it up.
So what tyres would be better noise wise, so long since I had RSRs etc.
Ideas?

AD08Rs are the quietest I've found.
