I saw that Aaron's shop in Seattle is selling with modifications to fit shimano hubs in Big Dummys,
the higher spoke count accommodating heavy loading, 135 because that is what the rear is on those..
Ah, Ha !
Any how Less than a Phil tandem cassette hub,,, Though, Their freewheel hub, is my fave.
Old 6 speed on a, 48 spoke hub, I only broke 1 spoke, but since I had 47 spares already in the wheel..
I just did a little wheel truing to balance it again. & rode on ..
