I've been? behind Terry's (highflyin's) SX.? The wakes between the SX and my X22 were a lot more similar than I expected.? Honestly, I'd have to ride behind it again to give a good review of the differences...I've only ridden behind Terry's rig once, and I believe we had about 1800-2000 lbs of ballast & people (which is about what I usually ride with anyway).? It seems like the transition, shape and size were all about the same comparably loaded -- the SX may be a touch bigger than my x22's wake, it was also a touch wider with the same length rope.? But the X22 seems to have a touch more pop than the SX (Terry, any comment? It caught him by surprise first couple passes behind my boat -- he was getting up there), and I think the X22 can handle more weight (I can get mine up around 2600-2800 lbs, if I don't mind waiting forever to get on plane).? But then again, the X22 has bags all over the floor to get there.
All in all though, they are very comparable.? And the size/shape is almost identical.
And about wake shapes in general -- everybody describes them differently and uses different words for different things.... and in the end, it really all comes down to personal preference.? For me, I like a fairly rampy wake, but still steep enough that you don't need to build it huge to get a good, solid kick.? My two favorites have been the Tige 22V and the 22' Supra Launch LSV/Mobius XLV.? ?In comparision to the Tige, the Supra/Mobius has a shorter transition and steeper wake... (though still on the rampy side).?
People often use the Malibu Wakesetter as the extreme of a rampy wake with a long transition, and the Nautiques as the extreme of a steep wake with a short transition.? I like the Malibu wake, but don't like the ramp to be too big or I get thrown.? I'm not a huge fan of a really steep wake like the Nautiques have because I feel like I need back-work after I hit the wake.? But I approach the wake a lot faster than most do, which makes the steep wakes feel very abrupt. So to each his own!!
