I really like the idea of HSB and SMB instead of LMB. I also found a source for pumpkinseed sunfish. I guess they are similar to RES. Snipe how did you keep the SMB alive for 7 hours in the car?
I have the necessary tanks with aeration and O2 to move fish although it doesn't require much to transfer 2" SMB. You can haul 100 2" SMB for 8-10 hrs with a 20qt cooler and a small stone aerator with lower water temps. I would definitely heed Bill Cody's advice on HBG vs BG though. BG are just too prolific for smaller gape SMB to effectively control them.
