I built up a Phil 32H fixed/ fixed hub to a open pro rim this year. I have about 1000 miles on it. I do mostly open road riding, not much in the city. It is a great combo, totally rock solid and reliable. It is also very comfortable. I weigh about 190lbs. and I used 14/15 buuted spokes.
My previous wheel was a Promax disco on a Alex 19?? rim. That was also a good setup but nothing like the Phil. I think the biggest difference is the bearings and the lockring threads. I also do not get any slipping in the drop outs with the Phil. The spacer is stainless steel and really grips the drop out.
I thought it was all hype about the Phil hubs but it is not. They really are nice!!
