Any 24" blade should work, so you can get a Rain X if you prefer that brand but beam type blades don't work well for the monowiper in my experience. I use a Michelin hybrid blade I think it's called Stealth It's basically just a metal frame blade with a rubber cover over it. The little square holder thing at towards the base makes contact and keeps it in place so it wipes well down there throughout the articulation.
