GW - the key would be to stock enough LMB to keep their numbers in check so they don't stunt. One of the most impressive big LMB lakes I have fished in our local area had a GSF for a forage base, the GSF did an excellent job of keeping the LMB fry/population under control until aquatic vegetation got out of hand. Prespawn LMB at 18" were always over 5 lbs sometimes pushing 6 lbs.
