[Closed] Seek parts advise with 29er SS project

Hi there,
- excuse my German but there might be some errors below -

I am currently completing an [u]Inbred 29er single speed[/u] and would be very [u]grateful for any advise regarding [b]final component selection[/b][/u]. Main questions: brakes, tyres, cranks

Here's the list of parts and further down the brief of what I expect from the bike. Any comments and recommendations welcome!

[u]THESE ARE THE PARTS I HAVE ALREADY[/u]
Frame: On One Inbred 29er 16" SwapOut
Fork: On One Carbon
Headset: On One Smoothie Light
Seat: SQ Lab 611
Seat Post: Thomson Elite
Seat Clamp: On-One Forged Alloy

[u]THESE ARE THE PARTS THAT I AM CURRENTLY CONSIDERING[/u]
Stem: Thomson Elite, 50-70mm, 0° or negative°, 25.4
Handlebar: Salsa Alloy Moto Ace 25.4 (-> light, stiff vs. adding compliancy?!)
Grips: Odi Attack
Disc Brakes: Shimano XT M785 (-> should be light, hassle free, mud resistant, maintenance friendly)
Wheelset: HOPE HOOPS PRO3 SP-XC3 with Stans Crest (-> should be light but robust and relatively stiff)
Tyres F&R (?!): Schwalbe Racing Ralph (-> should be light and allow for controlled drift-ability, smooth transition into corners, mud not important)
Cranks: Rotor Agilis (-> should be light, stiff, simplistic)
Chain rings: Rotor, round
Bottom Bracket: Rotor
Chain: KMC X9-SL Superlight Chain

[b]The bike is meant to be:[/b]
- round steering and sweet handling on flowy and tight single-track for fun-biased XC use with the odd bunny hop
- smooth transition from straight to cornering on hardpack and looser forest tracks (that's Norfolk for you)
- predictable driftability and controlled grip, good front-end bite more important then rear wheel traction
- relative compliant ride
- lightweight (<10.5kg) with focus on rotating mass,
- no fuss reliability and hose-down mud-resistancy
- reasonable priced (<1,200,--),
- easy to upgrade to Dingle and gears

The bike shouldn't be/doesn't have to be:
- fancy
- color coded
- heavy on brand names (at least not for the sake of it)
- ultimately stiff
- ultimately grippy
- exceptional in the mud

Many thanks for any comment!
