That looks like a great idea. It would certainly be less disruptive.
As far as setterguy's concerns, I think they might be valid for some species of fish. But the GS seem to be dumb as stumps. I can wait a few minutes, throw another hand full of feed out and they are back.
I think it is important to point out that this is in a 1/20th acre pond. The fish likely are very hungry and can't run far away. I would not expect as much success in my 3 acre pond.
Something I think would work is throw it at night when the HBG are sleeping near shore. I have not tried it with the cast net, but I actually picked up a small BG in my hand one late night in less than 6 inches of water.
