I don't use hoods. Basically because of the added bulk. The main reason is that I just don't shoot with light sources inside the frame... And I don't shoot under direct sun unless the sun is totally or a bit behind my camera... And all my lenses have a filter on them always, (yellow, uv or warming) so those extra milimeters help too in case of lateral sun... I don't remember any flaring or washed images in many years... I own hoods, and even carry rubber collapsing ones just in case, but I just prefer to avoid those scenes instead of shooting them with a hood.
Cheers,
Juan
