The present invention provides a slip system for frictionally engaging a temporarily set body, such as a packer or a whipstock, within a wellbore. The slip system comprises (1) a plurality of slips; (2) a tubular slip ring for holding the individual slips at an end; and (3) a tubular cone body having beveled surfaces for receiving the individual slips when the slip system is actuated. Each slip has a first end that defines a tail, and a second opposite end that defines a slip body. The tail and the slip body are integral, meaning that the intermediate shank portion of prior art slips is essentially removed. In its place, a dovetail geometry is provided within the tail, creating an increased tail width at the end of the tail opposite the slip body. The slip ring has a plurality of pockets, with each pocket being dimensioned to receive the dovetailed configuration of the tail on the respective slips.
