This is why there are so many different brush types because there are so many different cleaning styles!
I had an extreme natural hybrid for around a year and it was still like new, except for the edges of the stock. I gave to my wife to use who's half my size and weight and now it's buggered, flat as a pancake.
I used my new one today and it's a real pleasure to use, I hate when a brush just collapses on the glass. I also got an extreme stiff which is also nice to use but the feel of the hybrid is much nicer.
It's a different breed of brush altogether and is plenty adequate for most maintenance work, if you can work the brush how its meant to be used. I'll keep the new one away from the wife for sure, and I reckon I'll get another year plus out of it no problem.
