Would need to know how much play you do have in your chain at the tightest spot as you state you don't like much play. A chain that is too tight is always noisy. Maybe move the wheel forward by a mm or two just to see if noise goes away?
Also important to keep it well oiled in case you didn't know that already :-)
As for size, I run 34/16 (yes 34!) and it is completly silent. 3/32 front and rear with 3/32 Wipperman nickel chain.
