Back to the topic, if you were trying to find a negative angle (and forgetting about the safety concern), they jump the open ditch at the top of the hill, say 5/6 furlongs out and will now have only one fence to jump from there till after the home turn, which is 2 furlongs out. Is that a long way with only one fence and will it put the emphasis on faster horses as they can get away and even if they are not the cleverest of jumpers, they could have the race won by the new second last and it will be easier to jump. I'm not advocating that the fence shouldn't be moved, but will it create a new dynamic?
