With only stocking 300 CNBG in a 1.1 acre pond, I wouldn't worry about them getting too far ahead of the bass when the bass are stocked in the Fall, in fact only stocking that many I'd recommend waiting for the CNBG to pull off a few successful spawns before adding the LMB. You are fine stocking them this Fall. Only throw 100 in there, you can always add more if needed, but with a great forage base those LMB will be over 12" long in a year.
