Go for it! Should have no problem with what I've seen of Gauge on your videos etc. I would make sure that on the first few birds that you have only your buddy shoot, and restrain her with a light trailing check cord with slight pressure just to be assured she doesn't break. Easier to prevent and condition rather than to correct. Then if you want to shoot, which will be more of a tempation for her, have your buddy apply the tension to the check cord, praise her, and walk over and heel her and send her on the retrieve. Gradually release the tension on the cord until she's steady with either one of you before you both go to shooting at the same time. That's when you get to find out if all this year's worth of work has paid off perfectly. I bet she passes with flying colors 'cause you've done it right!!
Put 'em on the water (leave her a cripple or two, as well)!
She'll make you proud!
Teal are mighty good eating, lets hear the results. Take your camera.
