i have not tried monopod but during an event shooting, i notice alot of pros using monopod.
However, tripod will be more versatile since it can be used for creative long shutter shooting also just bit more cumbersome.
Anyway, im using a < rm300 benro tripod which is quite sturdy and easy to bring around.
sometimes it felt like life is screwing me upside down and over
but fear not, for what doesn't kill me makes me stronger
