No experience with the blur, but having a Ranger v1 this is something I consider too. Your build seems a little heavy. I forget the exact weight but it’s under 30, and that’s with a 140 fork, Cane Creek DB IL, big rotors, 4 piston brakes, alu bars, and big (but reasonably fast) tires.
The problem I see is that no matter what, the Ranger frame is heavy. Even I swap back to Sid fork/shock, drop the rotor size, and go to carbon bars, all the low hanging fruit, there is still at least 2 lbs more frame weight. OTOH the Ranger climbs pretty well and eats up descents.
