If it has a boat buddy then get rid of it. Replace it either with the new Ramp N Clamp (Which I have no personal experience with) or a 3 piece roller (The one for a 3" bracket) and safety chain. Me ('00 230 VRS) and my friend ('07 X2) both did the latter years ago and have vastly preferred it to the Boat Buddy.
Don't forget the safety chain as you need redundant attachment points to the trailer. The winch is your "primary" and the chain will be your secondary connection should the winch strap break (They do often break too especially if stored outdoors).
As others have said, approach the trailer slowly and make small adjustments. I come in slow and let the guide poles guide me in. Once the boat is straight and settles between the bunks I give it some throttle to bring it up close to the bow roller and then leave it in gear while I go to the bow and attach the winch strap.
Also, many people do it but never disconnect the winch strap or safety chain until the rear of the boat is in the water when launching. If you do you could end up prematurely launching that X-Star right onto the concrete ramp. I've seen it happen.
