That lake sounds awesome. Do you have stocking numbers of the forage? Obviously that's a big job (would love to see it!). I'd wait *at least* 6 months. I waited a year and it was a good idea because the SMB were adults. Remember they grow a bit slower than the LMB (mouth/prey size).
For the mixed bass pond, IMHO This is good:
Forage Day 1
SMB + 6 months from Day
LMB + 6 months from SMB
This is better:
Forage (minus BG) - Day 1
SMB + BG 6-12 months from Day 1
LMB 12 months from SMB +BG
All of that would depend on stocking ratios and sizes of stockers. If you're doing more adult forage, then time can speed up. Ewest always recommended, and I agree as I did it, stocking various year classes of forage. It speeds up reproduction and ultimately gives you a great base. 100 acres is big, and patience will pay off years down the line in building forage base and letting it grow before it gets hammered. BTW, are you going to be supplemental feeding anything in that monster?
