Kinda what cumberland said: Xstar is meatier than the x-25 and stock Vs stock the 25 may appear taller/steeper. You will for sure want the extra weight, who wouldn't! If I were you I'd get those bags ordered now so when the time comes you can load that star up and play with it like it was meant to be played with! I love the star wake!
Some even say the star wake is even better when you leave the back tanks empty and fill the rear bags. I havn't rode like that though.
