I have a 98 Malibu Echelon and I am considering upgrading my boat by five or so years. I'm thinking about an early 2000 response (maybe '03 to '05). I've skied behind an LXI of that era and I don't remember being very impressed by the wakes. Can anyone comment on the wakes, driveability, etc. of say an '03 response (not LXI) vs. the 98 Echelon (or 98 Response)? I assume the LXI has a different hull than the closed bow standard response. Does anyone know when the hulls changed? Does anyone know what the first year response is that could have zero off added to it? Thanks in advance.
