[Closed] Polished silver Shimano 28h hubs? Which ones and where to find?

I'm upgrading up my new steel Cadore with 50 mm carbon rims (saves 300g rolling weight, makes the tires 1 mm wider, is more aero and looks better IMO)

It currently has lovely 36h tiagra front and rear hubs (4400 series?) which is a bit excessive for a stiff carbon rim. 28h front and rear should be plenty with CX ray spokes?

Any polished silver 8-10 speed shimano hubs I should look for? 28h front and 32h rear would also be fine. I believe tiagra made a polished 28h front hub, but having a hard time finding one.

EDIT: Found a pair of 28 hole hubs on ebay for $100 delivered..
