Brettski,
Very cool stuff your making there!!
I'm wondering if your putting it all in the same place is counter productive? Is it ideal to have them all so close together, or spread them out in groups of two or three all around your lake?
The reason I ask is that they will attract you fish to them, and with high concentractions in one area, you wont have as many in other areas, and you might also limit how many fish are actually able to take advantage of them.
Again, I don't know about these things, I'm just curious.
Thanks,
Eddie
