I have a 2016 SkS and a 2017 sba and have to say unless my wife wants to ride I never ride the sba. Even if I'm on tug hill bombing the trails there's always the possibility of finding a sweet spot that's going to make me regret having the wrong sled and here's why. the sba has a 2.0 track, boost, and mtx cna skis how every it can't hold a line side hilling not to mention it takes more than twice the commitment to get it where you want versus a little body language and twist of the bars to put the SkS on edge. Also out west in fluff even with boost it a struggles to not get stuck and if you do it'll take a lot more work to get it out on plane. Once again roll over the SkS and pull off like it never happened. With that benig said it's still a good sled for what it is a crossover however it's no means a 144 mountain sled and nor will the SkS 146 be. Not even close.
