Abstract
The differences between two standard Monte Carlo models, Lepto and Ariadne, for deep inelastic scattering at small-x is analysed in detail. It is shown that the difference arises from a `unorthodox' suppression factor used in Ariadne which replaces the normal ratio of parton densities. This gives rise to a factor that qualitatively is similar to what one would expect from BFKL dynamics for some observables like the energy flow and forward jets but not for the 2+1 jet cross-section. It is also discussed how one could use the 2+1 jet cross-section as a probe for BFKL dynamics.
