Chris, I'll completely echo Cody here. If you're targeting SMB, and have the choice (i.e. they're not in the pond yet) don't go mixed sex BG. Seining will be too much and won't do it well. Even catching would be HARD to keep them down enough. I've watched this for 2 years with 20 SMB - they don't like BG unless they're tiny.
I'll also FULLY agree with Cody on the male only BG pond. And I've heard that if you have tons of mixed sex BG in a .15 acre pond and have to seine and sort out the females it's a lot of work, so it might be better to start with male only BG's. Although less sporty! I think a male only BG, with a few SMB, female LMB, and a couple RES, along with GS and FH sounds like a FANTASTIC pond.
