I race cocks widowhood and hens natural,one thing i would say mate is no matter Wat system you choose to race,plan it and stick with it.I think the worst you could ever do is come to the 4Th or 5Th race and because u are being beaten by the opposite system,change your own.No good,you will end up worse.Try a system one year and if it don't work swap over the next season.
