Speedbird,
When you get widowhood cocks on form they fly in straight lines and at pace. When a kit of 20 cocks split into different directions it's a joy to see. Personally it's my favourite part of the season because you know you've done your job.. It's then down to the birds and the motivation.
Widowhood cocks that circle and clap around are not what you want, these birds are often off form or tired. Training does ensure that the birds are doing the 'time on wing' but if overdone it will retard the birds even more.
This is just my opinion though - I know people who win out of turn and they train every day of the week.
