I would wait and see what skis the 2018 models get fitted with. You 2018 guys may get lucky with other type skis?
But yeah if they get the Tuners again you will be looking for the alternative. My dealer had told me to put a set of Snow Trackers on mine. That was his recommendation, so I ordered a set. They were wrong set and I would have had to wait for another shipment which was 2-3 weeks out, so I chose the XS Curves with Woodys Slim Jims. Blue ones are a good match for my sled color.
Also a post on this site about using the Doo pilot skis, can't miss that post, I think it grew into over 20 pages. Many love those. But either way, plenty of time and many topics on skis for your new sidewinder. Happy reading!!
