Carole, it's just an idea i thought of after i'd started the topic. I haven't even thought it through properly, it wouldn't have to be yd/lb. And eventually by doing it advance and retard the handicap would catch up with those fast lightweight or advance those slow heavyweights. I'm sure someone can come up with something better.i perosnally still think timed is best even for the retard system wot if had a 30lb dog and it just cudnt get close did u do u have a limit on weights? we do have a limit of 21yds and have had a couple that shud have been off more then 21yds but we owe them it so when they win they wont get pulled.
