I tried the 3/32 Shimano freewheel with the 1Z1 and the drivechain is still noisy, although admittedly not as much as track cog with 1Z1 chain. I also swapped the rear wheel out and the grinding rattle is still there, no difference. Finally, I decided to swap the 1Z1 chain for a Shimano Nexus NX10 chain and the rattle is still there but not as much as 1Z1. I am just wondering if I have a bad combination of sprockets and chain or perhaps expecting too much for it be silent. It is a carbon frame so maybe that amplifies the rattle?... There seems to be a lot of up/down movement when the chain is in motion, which is odd.
