I really like the MKS GR-9 as well. I bought a set for myself 10 years ago, repacked the bearings a couple times over the years, and have done probably 90% of my miles on them without problems.

I think I might even buy another set this year!

I do have small, narrow feet though (US 8.5, EUR 41). I can see how these would be a problem with size 15 or something.
