  We discuss a recent study on high-energy jet production in the multi-Regge
limit done with the use of the Monte Carlo event generator BFKLex which
includes collinear improvements in the form of double-log contributions. We
will show results for the average transverse momentum and azimuthal angle of
the final state jets when at least one of them is very forward in rapidity and
another one is very backward. We also discuss the introduction of a new
observable which accounts for the average rapidity ratio among subsequent
emissions.
