So we practiced again.

1. First a couple of straight metal retrieves. He needed additional commands to pick it up. I worked a batch on holds and carries, and making him move about and actively hold it, even when I tapped it.
   
2. Metal with one unscented metal. Worked and after some delay, brought back the scented one.
3. Metal with 5 unscented metals. worked and brought back scented one.
4. Metal + one unscented leather. First try brought back leather (though had indicated metal). I just stared ahead and he, after a pause of 5 seconds, went back to bring the metal one.
5. Leather + 5 unscented leathers. worked and brought it back.
