technical XC rather than interminable plodding round the edges of fields on dull dull dull bridleways?....youll be wanting some rear sus. in my book then.....ride further/be less-fatigued/hit technical stuff at speed that a hardtail will shy at...
whats your budget?
trek fuel or Specializeds spring to mind....
Got to be on the short list, if budget allows.
