The "Cover Slide" series was designed after repeated verifications on the assumption that it will be used in a back slide setting that invades from the landing point toward an obstacle. The combination of ultra-high specific gravity material mixed with plenty of salt and wide fat body shape creates the optimum sinking speed and sliding distance. Even complicated and intricate covers that could only be captured with rigs with sinkers, such as Texas rigs and rubber jigs, can now be easily captured with no sinkers.
