I use to fly roundabout, but this year choose to fly only the cocks on widowhood, the reason was that when on roundabout, if you drop a hen or cock, then there is no incentive for the mate to race home, also found roundabout to be a lot more time consuming. Saying all that, I did have success flying my hens on roundabout, but I am happy with the way my cocks have been flying on widowhood this year, and always guaranteed their mate would be there waiting for them. JMO Good luck with whatever you choose to do
