Where are you going to get the CP from? I don't know of a single hatchery that sells them. CP can be very suceptable to predation if there is little cover for them to take cover in.

I would utilize SMB and RBS, giving the SMB a head start until they're 8-10" before stocking the RBS. Then when the SMB are at 12", you could consider PS. I wouldn't stock BG in a far northern pond such as yours unless stocked with LMB and making sure your LMB are 12" before stocking them.
