Different search strategies for supersymmetry have been employed by the LHCgeneral-purpose experiments using early data. As proven by their early results,these strategies are promising, but raise the question of how well they willgeneralize for the future. We address this question by studying two thousandphenomenological minimal supersymmetric standard model parameter space pointsthat come from a fit to indirect and cosmological data. We examine the 5 sigmadiscoverability of the points employing a typical ATLAS-type search based onmissing transverse momentum (MET), a search based on an optimised MT2 cut and acombination of the two, taking into account standard model backgrounds. Thediscovery reach of the strategies can depend strongly on the systematicuncertainty in the background, subject to the stringency of the cuts and thedetails of the background simulation. By combining the MET and MT2 basedstrategies, with an integrated luminosity of 1 fb^-1 (10 fb^-1) at 7 TeV, 4-8%(42%) of the points are discoverable, depending on the systematic uncertaintyon the background. At 14 TeV and with 10 fb^-1, 96% of the points arediscoverable. While the majority of points can be discovered by both strategiesat sqrt{s} = 14 TeV and with 1 fb^-1, there are some that are left undiscoveredby a MET search strategy, but which are discovered by the MT2 strategy, andvice versa, therefore it is essential that one performs both in parallel. Wediscuss some of the factors that can make points more difficult to observe.
