To be fair it seems like you don’t know what you want. The K2, the Kato, and the Mission are vastly different bikes.
You think the 69 head-angle on the Kato is twitchy, yet your K2 probably has a old school 72-74 head angle, while the Mission is full Enduro with 66.5 and a 36 fork.
You talk about hitting jumps yet are leaning towards XC geometry while pointing at Trail and Enduro bikes that have nothing in common with your K2.
In my opinion you need to get used to modern bike geometry if you want a Trail or Enduro bike, and then pick a bike for the type of ridding you do. Your K2 almost has nothing in common with modern Trail/Enduro bike geometry, even Trail Hardtails.
I’d suggest renting or demoing any Enduro bike because I don’t think you understand the use case or feel of a Mission 2 type bike.
Also do not spend 1800 on a 26″ bike in 2017.
