if there are alot of casters attending they may break you up into two groups, and one by one you stand up to the oche and belt one down but must be in court which is set with a measured centre line and two outer lines set at 30-degrees from the centre line on each side, then place you rod on a rack and the next guy goes and does the same untill all have cast then it just a matter on winding in as you walk up the court to where your lead has landed, take a measure and as you beat that you move your measure up and so on,, thats it in a nut shell really.
Danny was using a 16ft Century rod that had "special" written on it not sure if it was a "Big Danny Special TT-R" or not but the carbon did not look like any other century ive seen him use before.
His reel is a self tunned Abu 6600w (the "w" stands for wide) these can be got in either black-max or promax versions "IF" your lucky enough to come accross one these days,,,
I hope this explains it for you.
