Nothing wrong with your idea Shaun.

The problem is selecting the runners to follow [where I also had problems].

Perhaps looking at promising 2yr. olds might be a better course to follow.

What you have selected are horses with good form behind them, not in front of them.

Biaggio has to come down in class and to 1100m. and has been up since Jan.

Bradshaw has won only 1 from 14 starts and that was 1 win from 9 starts last year.

The rest of your runners seem to going backward form wise too.

Can't see sense in following them but your idea is sound enough.

Sort out some [young] runners on the up and you should do OK.

Cheers.
