We present benchmark points for Pure General Gauge Mediation (GGM) models specifically optimised for early LHC searches. The pure GGM set-up is as defined in our previous paper arXiv:0910.2674: namely we adopt the minimal set-up in which B_mu is generated only through gauge interactions, and as a result tan beta is a prediction rather than an input. The only input parameters are messenger masses together with two independent scales which generate gaugino and scalar masses. The parameter space favoured by current experimental data includes an interesting region with light gluinos (m_g < 500 GeV and relatively heavy squarks) and a bino-like NLSP where early discovery is likely. We also find interesting regions of parameter space where the NLSP is a stau or stau/neutralino co-NLSP and the squark masses are relatively low. We present benchmark points which are typical for each of these three regions, and give the spectrum, branching ratios, and also the overall 2 -> 2 cross-sections.
