Both have their advantages and disadvantages - snagging of the running line is a major obstacle - its easy to stand on it on the platform and unless the ground directly infant of the platform is nice lush grass the weeds have a tendency to grab hold of it and stop the cast dead in the air (dandelions are the strongest weed ever
)Owing to my casting style (& body weight ~210lbs/15st/96kgs) most of the platforms I've used at WC events do not have the stability to utilise the transition of body weight movement on the distance events (only speaking from 2006 onwards).
Me personally, I prefer to cast from flat ground (a stable footing), I can remove 10-15m when casting from a platform which isn't great, it would reduce the amount of infrastructure required to host a WC event.
