I've tested the 1.75" x 6" toroids in the brushed and polished  finishes
years ago, and didn't see any difference in performance.  My 4" x  13" toroids
also have the brushed finish and perform well.

The end user could polish the brushed toroid, but it would be a lot of  work.
I didn't mention it, but I will also offer the toroid in as-spun  condition, 
$70, for those who wish to do their own finishing.  In the as-spun  condition,
there are minor ridges, or shading blemishes, etc. which would need  to
be sanded out first before using finer and finer grits, before using  the
final buffing/polishing.
