i've found they're are a bit loose, especially at speed.
First of all - you really *need* the wind deflector on the driver-side blade at anything over 100km/h.
You also need good earth connections around the dashboard - I thought my windscreen wiper motor had almost gone, when I realized it was all down to lack of lubrication *and* poor earth connections. If this is not in good order, the arms will struggle to come back down, once the wind has helped them up
Are there any close matches or originals available anywhere?
I have successfully used standard wiperblades with built in deflectors - you just need to find some which match the arm. I think I just located a Talbot blade, and went have a look. The one I ended up with is slightly longer than standard, and has a full length deflector. When I'm near my garage again, I'll see if I can find the exact type I found usable.
The arms themselves however are fairly easy to sand down, and repaint. I gave mine a thin layer of cold galvanizing spray, before spraying them glossy black. The glossy I think helps them stay clan and dry. (well, when its not raining, of course
)
My paintwork may not last for ages, but then again, its easy to redo.
