I had an original 853 Slackline and loved it. Sold it and bought a Kingdom Bike Vendetta2. It is, hands down THE best bike I have ever ridden! Raced it at the Dudes of Hazzard enduro and it did not put a foot wrong. The Dudes is pretty knarly test ground! (Came 3rd)
The Titanium is pure bliss. It is 650b, long low and slack, 31.6 seat tube so can run 150mm stealth dropper, 142x12mm rear end like all the enduro bouncers. I am running a dual position pike which is perfect for up and down. And can get it fitted with bottle mounts.
I also have the new carbon Nomad and the Vendetta2 is much more fun! You won’t miss your full-sus guaranteed.
