I owned the PV-8 (the one that starts generating at lower wheel rpm). It was certainly light and worked well, though for some reason I noticed more vibration with it than with certain other dyno hubs. This vibration was noticeable but not really annoying.
OTOH, doing spin tests, both with lights on and lights off -- the carefully controlled technique was to put the bikes in a stand and spin the wheel by hand on the tire as fast as I could -- the PV-8 lasted only half to 2/3 of the revs of the admittedly lower powered SON 20 R; OTOH again, the PV-8 was attached to a considerably heavier rim and tire, and those 700C, while the lighter rim/tire for the SON was 1.25" smaller in radius. Upshot, for me: If I could afford a SON Deluxe (which is the same, basically, I think, as the 20R), I'd buy that; but I'd choose the PV-8 or, probably, the lower powered but less draggy SV-8, over the best Shimanos.
