i get wot u r saying gaz we had mickey whizz 50lb out of a 38lb bitch and mickey mouse 22lb all i can suggest is either scrap sup scratch or dont run if u dont want to race against a big dog a bit like heavyweights withdrawing for givin too many yards away. if u were to stagger a supreme scratch race off times or weights or wotever IMO it wudnt be a sup scratch race, u wud have to call it the big dogs staggered handicap final or somat lol
