I am adding in Japan us and NZ jump jockeys and trainers hopefully with portraits to go with my jumps pack, however I am not sure whether I should retain one jockey to one trainer each. So currently I have a total of 8 Japan jockeys should I get 8 trainers to retain one each to or should i leave them unretained? Another problem I have encountered ( I've only done Japan so far so I don't know about USA or NZ) is that in Japan they ride a lot lighter over jumps so the minimum weight varies from 8,0 to 9,11. Whereas tony McCoy probably one of the lightest is 10,0 on the game. Again any hints on his? Do I leave them as they are or do I raise them? Does the game take into account 'dead weight'?
