Anyone find larger replacement blades that work with stock rear wiper arm?

[Snagtooth]

I found plenty of threads on the rear wipe arm replacement. However, a little trimming with an exacto knife will allow the stock arm to pivot up for cleaning so I hate to replace it since it isn't really necessary. What I would like is a larger blade that fits the stock rear wiper arm.

Walmart has a 16" TripleEdge blade that should work, but has anyone found a larger blade size that works with the stock rear wiper arm of my 2008?

Any tips are appreciated. TIA.

In case you haven't found a solution by now...
I've replaced my rear wiper with a 20" blade from Valeo. I would definitely recommend upgrading to a longer blade for a better wiper cover on the rear windscreen, even if you find that this particular model doesn't fit on the US Prius. My replacement wiper model details are: Silencio X-TRM UM660.

There is a thread on the UK Toyota Owners Club website started by Stompe. Valeo's low profile flatblade technology was recently reviewed by Autoexpress magazine.

I use the blade from my previous car which had a single wipe blade set up (Merc E- Class) I think its 22"
