Well I ride a 16" 456 Summer season with 110mm travel forks, 2x9 drive and a dropper yes it's the Old, old version now, but it does do "XC" (gets pedalled about), and it's fair share of "DH" type riding, does that combination qualify as "Agressive XC"? anyway, yes it's heavy, it's made of old gas pipes, but the geometry is pretty much bob on (IMO)...
You want a bike you can pedal to/from trails; sensible front triangle sizing so you fit on it, Slack HA so it can handle the steep stuff and it doesn't cost the Earth... Sounds like a 456 of some sort.
Steel if you don't mind the mass (although is the current "EVO2" lighter than the older versions?) and you are trying to work to a budget, or Carbon if you can stump up ~£400 and want to save some weight...
Other options might be:
Dialled Alpine maybe a PA
Cotic BFE or soul?
BTR Ranger (already mentioned)
SC Chameleon maybe?
How flush are you feeling? how lanky are you?
