Earlier this year I bought a 2018 Santa Cruz Tallboy C. This is my first full squish mountain bike, and it is awesome. The thing just floats over rocks and is much more forgiving than my old hard tail. It has 29" wheels, a 12 speed cogset, disc brakes, and a dropper post, all of which make the bike completely different from what I'm used to. Comparing times on Strava, I am faster on descents and any reasonably bumpy sections with this bike, which isn't exactly the point of getting a bike like this, but it is nice. There are trails I had stopped riding with my old hard tail because they were not fun that this bike makes fun. And that's the point.
