do the wake models differ from the SP models in that they have fillabale balast which creates a better wake experience?
Yeah, there are allot of little options that are available standard on the wake model but not on the 180 SP
(Tank Ballast, Tower speakers, Touch screen helm, Single shift lever, Wrap around seating, Wakeboard racks (swivel), Light bar, Swim platform storage, Transat seats, Stainless rub-rail, Usb control Stereo, 125W amplifier, and a heater.)
Probably more but that's what i got on my list to compare.
