I'd go a bit more conservative:
- fork 120 or 110 mm, in a 67,5 - 68 degrees HTA, respectively;
- fast as f...k, shortest chainstay possible; as light as possible;
- nothing wider than 2.4 tires - max 2.5 (but that's just to clear some mud, 2.35 are perfect for me);
- double RD hanger: either UDH or traditional;
- should take at least oval 36T, even oval 38T chainrings;
- internal routing;
- speed machine, for sprinting and cross-country eliminator (XCE) racing
- capable on downcountry, but nothing to compete full-sus bikes.
- a platform for tweaking and experimenting (so, as versatile as possible to newer or older tech).
