I have an '06 X2 and my wife can surf the stock starboard wake all day (she rides goofy). i am 6'2" and about 250 lbs and ride the port side. I have a hard time staying in the pocket with the stock ballast. I either run into the swim platform or lose the "push" from the wave. Our board is a 4'6" and I think that is a little small for me as well.
For Christmas I got the 1650 lb X2 piggy back system from wakemakers and a new 5'0" CWB surf board. I cannot wait to get out there and try it out! All this and MC releases their "Best Summer Ever" video on FB - I am going crazy already! LOL
