Well, after several recommendations I replaced the wiper blades with Bosch Aerotwin retrofit. I can't comment on wiping performance as it's either been dry or the Z4 has been stuck on the drive due to snow since.
However, compared to the OEM Aerotwin fit on our E92 3-series, the fitment is pretty fugly. The 3-er has flat arms, with flat blades, whereas the Z4 has arms that extend out, a big fat clip and then flat blades.
TBH I'm tempted to go back to the traditional wiper blades next time round.
