If your looking for versatility then a Comp Ski Boat probably isnt the best choice IMHO... A nice boat you can ski behind with a decent wake and still perform well in the middle of the lake ON A WEEKEND while meeting all the "family" needs, space, etc, is what you need. My wife loves to ski, but the Advance doesnt meet HER or the KIDS need to bring along a bunch of STUFF and/or friends...
Personally, a nice 21' SeaRay will meet all those needs and still has a decent wake, but that means you downgrade to an I/O and I/Os are typically underpowered and a PAIN to maintain (unless you can do it yourself). Some of the longer inboard bow riders will probably do the trick but they can get pricey VERY fast. I've heard Moomba provides more boat for less $$ (much like a Bayliner) and they are very stylish (much like a Bayliner) but be wary, you get what you pay for...
For any boat your thinking of buying - look very carefully at the upholstery & the back sides of the seats for thickness/fit & finish, in the holds, engine compartment, under the seats, behind the carpet (if you can) and under the console for unfinished edges/shortcuts. Shop around a little and compare "apples to apples" with other brands for fit/finish & quality construction, through-hull fittings & cleats (not screwed into the fiberglass), electrical installations & organized wiring (not a jumbled mess), steering & rudder components, etc... In the long run it will pay off!!
Good luck buddy! We'll see ya'all at the Reunion!!!
