There should be 9mm refills available I believe.
I put Trico single-bladed refills on last year and can't say I'm too happy with them - quite squeaky and a little bit streaky. I previously had a Tridon refill and they were reasonable.
The Bosch ones, while sold at a premium, are quite well regarded and often used by OEMs. I'm considering the aero blade variant for my next change.
Interested to hear others' experiences as well.
Edit: This seems a reasonable deal
