My Riv (97 Road Standard) had Phil hubs (pre-"Rivy"), and I rebuilt the rear dishless with a 650b Synergy OC rim.
But, I ended up selling off that wheelset to a list-member because of the "freewheel issue". Aka, there are few freewheels available, with ever-dwindling gear selection and quality.
I used one of the DNP Epoch freehwheels with good results, but I convinced myself that those wouldn't be around forever. The Shimano 13-28 and 14-34 freewheels (and their clones) will be around forever, I don't doubt that. But I don't like either of those gear ranges.
Don't get me wrong, you could easily buy a 20-year supply (which would be, maybe 3 or 4?) of your favorite DNP or IRD freewheels and be set for a long time. And with Phil FW hubs, bearing replacements are cheap and easy (they take a very commonly available size).
But, I used it as an excuse to build a new set with a dynamo and a freehub, and sold the Phils to a new home (with new bearings, of course). And I love my 3 x 10 with an 11-32 cassette and road triple.
It's a personal choice, with good reasons in favor of each case. But no one can deny that the market has spoken on freewheels.
