@TNh20skier I was looking for the same things and settled on a Response LXi. I don't have much personal experience but seemed like the longer line wake of the 3 was worst on the 206 from what I could find, plus they were harder to find and seemed to be more expensive for what you got. The 197s are nice, but are a little smaller and the wife wasn't a fan of the step over to the bow (and the 7 capacity plate since she likes to take out other families on more social days).
The RLXi seemed to be the largest of the 3 without being too big a boat, has true walkthrough and was pretty good reputation wise for longer line. If you do more than ski, having the wedge as an option is nicer than having to mess with ballast in my opinion. This may be a bit wally, but the RLXi is the only one with a rear tow point standard (not supposed to use the nautique lifting rings), so you could use that on more casual days with kids and still use the back seat (if you don't get/want a tower). The 07+ has a bit more freeboard, is a little nicer ride in rough water, and is less likely to dip the bow with people sitting up there compared to the 03-06. The earlier model goes back to 03, so it could fit a pretty wide budget range.
