Methods for preparing metallocene-based catalyst systems containing an activator-support are disclosed. These methods are directed to contacting an activator-support, an organoaluminum compound, and a mixture containing a metallocene compound and cyclohexene or a mixture of cyclohexane and 1-hexene, resulting in catalyst systems with increased catalytic activity for the polymerization of olefins. The olefin polymers can be used to produce film products with high haze values.
