Looks like it.
The regular fatty is a hoot, lighter frame would be a bonus.
Bluto + reverb = win
X01, expensive consumables, but you could always go back to 1×10 (I think the mech and shifter will work, just adjust in the adjustment screws to stop the last shift) for winter, or sell it and go shimano 1×11 if that bothers you.
The original fatty wheels were a PITA to get set up with tubes let alone tubeless (which was actually easier). ANYTHING would be an improvement, and those look like new rims. When they worked they were fine, but they could be a right pain.
Worth £700 more than a regular fatty was, maybe, I’m not convinced by the cost of 11x SRAM parts, way too much if you’re a serial mech destroyer or ride in the mud a lot, but the reverb, bluto, possibly wheels, and lighter frame are worth a good amount of the upgrade cost IMO.
