Hey Ron,
Great to hear from you and glad to hear you will be back in paradise! June or September? That is a tough question. I would say most years the first week of June will fit your needs well. September is overall better for walleye and pike plus I'm sure the rockbass would be pretty easy to find as well. It is almost a coin flip but I bet if you went on a perch trip in Sept your mind would be made up very easily. Last few years or so we have been just pounding the big jumbos in Sept.

Hope I didn't just make your decision harder...
