I do prefer the sound of the 35/85 combo rather than the 24/50/85 combo as I'm not a big lover of the 24.
I already have the 50 though and its quite a cheap and cheerful lens so might just get the 35 and 85 and keep the 50.
It would however mean selling my 70-300 VR which to be frank, has not been used since I bought it from here!
Nothing wrong with 35/50/85 or even 24/35/50/85
