Write the notes for the heralds clearly as they will have to be able to read it. As some names are awkward to pronounce, it is often better to write down the name 'phonetically' so any novice heralds can just say what they read. For example, 'Cian' may be best written 'Key-an' so that the herald's don't mispronounce it.
When arrange the fights for each round, make sure that none of the fighters from the last bout in the previous round are then in the first fight of the next round. Fighters have to be given a rest. If this happens, you have probably rotated one list of fighters down the page instead of up the page.
