Great start, however in 1500 you can't be 1502, my advice would be loose the brace of pistols, they are generally useless anyway, they take away from his save in combat, if I were direct my attacks against the Champion he would only have a 3+ basic because his pistol means he's can't use his shield
Rock list, I would personally try to run one unit of guts and one of bulls, but that's me
I assume your sabres are 3 individual units? At 1500 I only use 2 but 3 is fine
