cheers Gavin, she will retrieve all day and is ball obsessed so I use both as rewards. I hide blinds and chuck em about when she isn't looking plus the occasional steady marked from heal, I am always receptive to any training ideas that I can use. Just to clarify I am keen to get a reliable stop particularly to a marked or memory then redirect, this is my main interest at the moment. Steadiness is improving as a result of the stop whistle training Imo.
you sound like you know your stuff, out of interest what is your history with gundogs ???
