Low energy Supersymmetric models have over 100 free parameters, the soft SUSY-breaking (SSB) terms. They can be explained as a result of stabilization of a scalar field in the string theory, called moduli. Such procedure produces a specific pattern of SSB terms that can exhibit distinct phenomenological properties. The simplest KKLT stabilization scheme leads to an interesting scenario known as the "mirage mediation". However, KKLT suffers from several problems that can be mitigated by strong stabilization construction. The recently introduced KL model, where strong stabilization is employed, leads to another SSB pattern of mini-split SUSY with anomaly mediation. In this talk, I will outline those two stabilization scenarios, and give a comparison of their phenomenological signatures.
