You figure a 5 pound bass is going to be 18"-20" in length or so. That means it would prefer to be eating BG in the 5"-6" range. Not too many brand new ponds have large numbers of BG in that size range to feed 1 let alone several bass of that size.

Also, there have been studies done showing the survival rates of larger bass transferred to a new body of water is often low. You can use that as an excuse to kindly turn down the bass offered to you...
