The jr ski in only 76 mm underfoot while the poacher for the adult in 96 mm so if a lot of snow fall at your home mountain and you plan on skiing a bit of soft snow, the adult will be the best option. However, if you get the jr, it will be better for groomers but you won’t be able to keep the jr for a long time because as you progress you will feel that your skis are to short. I would say get the adult version because the jr you will only be able to keep it for 1 season at the most. You can probably also get a good deal with the k2 poacher since its the end of the season. Or you can get the 2019 version which is unchanged from the 2020 version except the graphic and its also $300 which is $200 less than the 2022 version. And if you really want you can wait for the 2022 version, but it will be no less than $550 bucks.
