Bosch has got something like that neoform one now too - I use them on the Falcon, not too bad and you don't have those crappy metal brackets like on a normal blade...I think they might be pricey though $20 or maybe even more each...plus they might not make one short enough for a Datto

In Malaysia,it rain all the time...
Good wiper is a must...
I've been using silicone wiper till now since i bought it around 2003 for Rm70+...(Normal wiper cost Rm20-Rm35)
It still working fine but i use Rain X too..

I've been a trico neoform guy for a while now but this last time I tried the 'Trico Tech Beam Blades' that just came out in late 2009. They are super beefy and they have a new off-set mounting that lets the wiper arms sit ever so slightly lower. They look and work great. Cost less than the neoforms. Easy install. Got them online.

My personal favorite wiper blade is the Bosh microedge. Been using them for years.

You could try these, they are modern design and should manage the large curved windscreen well

Thanks guy for the good ideas. I didn't know that the rubber ever needed cleaning, but it makes sense.

I replaced the rusty springs in my arms (bit fiddly) and kept my standard blades, aftermarket were not that good. I found the best inserts to be the ones with the metal strips on either side of the rubber insert. Plastic backed ones dont last long but are cheap and silicone can be noisy on the glass.

i prefer silicon blades myself

I've found that the replacement blades are bulkier that the stock blades. They tend to lift off the glass at highway speeds and I think they pretty much look like crap.
I use replacement inserts in the stock blades. Even though the stock blades have loosened up a bit in 38yrs, they seem to work fine.

I tend just to use inserts, but I clean my blades with a soapy mix about every other week in the rainy season. It does no good to clean a window when all of the crud is still on your blade, plus they last much longer when cared for in this fashion.
