I'm in the process of moving back to the Kansas city area as well. If you wind up on the west side, Clinton lake and perry lake a both pretty good. The problem in kansas is always the wind, not so much on fighting boat traffic. If you find yourself on the south side, Hillsdale lake is a good option, and is practically across the highway from the cable, KC watersports.
Best of luck in your move, if you do in fact wind up out that way. You can pm me if you have any other questions. I don't have a boat, but have a pretty tight riding buddy with a tige 20v, slammed to the hilt. Also suggest you hit the cable first of april for fools fest, there will be a ton of local/regional riders around for that event.
