I like my Goldtec - even got a rare unetched version due to needing it urgently), but as mentioned they're not silver if that's an issue, the chainline is a bit weird (though I've managed to set it up within reason on a fixed mtb), and the aluminium washers are crap.
I've had a replacement set, but they're still smooth which means there's not much bite, and they're very soft. I use a chain tug on the driveside to stop slip, and have stuck 2x10mm penny washers behind the non driveside, to stop the allen bolt deforming the washer.
First set of bearings still going strong after 1000s of commuting miles, and quite a few hub-deep adventures through all manner of mud, clay, and animal by-products.
I'm getting paranoid about the nuts on my System Ex now though...
