I think Northerly is best suited to weight for age as he meets all others on fairly equal terms. I don't think there is a horse racing in Australia at the moment that can beat Northerly at equal weights. He is not the most brilliant racehorse but he certainly must be the gutsiest. He refuses to let other horses go past him and he eventually wears them into the ground.
He will get beaten again, and probably fairly soon, as in todays racing horses cannot go on winning forever (Victory Vein!). However at the moment we all should just marvel at this magnificent racehorse as he won't be around forever.
