I have the 2011 Launch 22v and love it. The heater is a nice feature to have. Also I'm not knocking the Roswell light bar, it is nice, but alot of people have had problems with the speakers. (Me included) They just are under powered. Another note on the stereo is the kicker amps that come OEM are not marine grade amps and could go out if subjected to a moist hot environment erm like inside a boat lol. Most boat owners end up customizing it anyway. So save your money and get some wetsounds or some XM7's
I also have the z5 and do get some good use out of it. To me its a bimini that stays out of the way and keeps the kids from getting sunburt. I do use the added room for a place to put a tube and a surfboard and some other boards but we rarely have more than 4 wakeboarders at a time. Yours already has a bimini so spending the added money for the z5 doesn't seem worth it to me.
The stock ballasts will do fine, but the only way you can know if you have too much ballast is when your boat is now a submarine. Just remember with all that weight loaded up to come off plane slowly otherwise you'll get a huge tidal wave over the stern haha
Hope you enjoy your new supra, and glad to see you up on the forums too
