The Leica 28mm Summicron hood is an abomination. Too big and too bulky.
Leica doesn't do a good job with hoods at all. As you say Vic, too big and bulky. I use the screw-in heavystar hoods on as many lenses as I can and leave them on all the time (don't use lens caps). The only lens this strategy hasn't worked for is the 24/2.8; I got vignetting/light falloff and I have to use the original Leica hood on that lens.
