Rathbun Lake in Iowa....any tips...?

Ahhh, yes. Lake Rathbun... First time fishing it come May. Never fished it. Looking for some tips. Got the hotspots map out.

Willing to trade. No problem exchanging. I can offer Lake Winnebago proper, upper lakes and Green Bay. GPS spots, patterns, techniques, speed, etc. (Plus a few key fried chicken spots!! 8 ) Its like having a guide, only less cost...
