all hubs will probably build the same, just calculate the correct length spoke.

I built up a dimension hub, but didn't get to ride it much and had the bike stolen

i'm currently using iro low flange hubs. they felt stiff in the beginning, but now the bearings spin very nicely. I haven't had a chance to feel what phils feel like though. I have some old dura ace here, the bearings aren't noticeably nicer imo, just loose ball.

maybe practice with cheap hubs and cheaper rims? probably not necessary, just a thought.
