It's a case of sensibly spacing your lenses. If I'm photographing in the city, I find a 20mm, 35mm & 85mm the most useful combo. However, if I'm going on a long walk in the countryside, I'll probably take 28mm, 55mm macro, & 105mm. Personally I would find the 24mm a bit of an "in-between" lens. Whatever wide you go for, you must aim for fairly close in foreground interest, otherwise your pictures are likely to be very flat and one-dimensional.
