Given the current state of the world....a better way to think about it might be "do I need/want a new sled sometime in 2021/2022......period."
If the answer is "yes", then the best/smartest time to buy is "when it's available," and not "when it fits my ideal riding schedule."
You could bail on a 2022 SC....SC this spring again, and be playing the same game this time 2022....any manufacturer. Then you've screwed up 2 riding seasons.
We have ZERO evidence to say there won't be similar supply issues through 2022. No one knows how long this will all go on, but we already know it won't be wrapped up 1st or 2nd quarter of the coming year. So the smart bet is that shipping/manufacturing challenges will not be absent by this time next year. I sure HOPE they will be....but hope in one hand, sh!t in the other and see which fills up first LOL
