i got through 3x PF30 BBs in about 4 months, all replaced under warranty, basically the seals failed on the drive side bearings,
the second and third I used which Wheels Manufacturing adaptors and they made the situation worse, trapped dirt and moisture between the adaptor and bearing, also they were a complete pain when removing the cranks, either ceased on the crank spindle or ceased in the bb, actually they got to a state when the BB bearing failed and ceased up completely and the crank was rotating in the adaptor like a shell bearing,
SRAM (through the bike shop) offered me the PF30 to BSA adaptor which I am running now, has been okay but has moved slightly in the BB shell, this is mainly due to the shop not using any loctite (although SRAM say you dont have to) and the SRAM cranks do not lock onto the BB (like shimano) instead use a number of washers and a spring washer to tighten everything together, extra washers have reduced the problem,
basically PF30 is awful whatever setup you end up with, but the wheel manufacturing adaptors were more worse than the PF30 to BSA,
