I would say this Grant...The Sparks great advantage is the weight (or lack thereof). I cannot tell you how many times I have seen people with 800+ lb skis struggle just to get them in the water. The Sparks are fun, easy to tow and an absolute delight to put in and out of the water. You can throw them around like the ski's of the early days. That said, they do come with compromises. They are only one year in, and none of us know how these things will hold up over the next several years! Will the plastic hold up in the heat/cold? Is the steering recall a one-off or are more problems to come?
I think we will all learn a great deal in the next year or so but I can tell you from personal experience that I have been absolutely delighted with the two I have! And the fact that they sip gas doesn't hurt either!
