If you mean 15 ft in a fly-fishing or sinking-tip context, the two best matches are Far Bank Enterprises Classic Sink Tip 15ft and Rio Classic Sink Tip 15ft. Both are built for Spey/two-handed setups where a 15 ft tip helps with line control and getting the fly down.
If you mean 15 ft depth on a lure, the best matches are the deep-diving crankbaits like JD / Eddy Lures JD 60mm Depth Master " Banana " and JD / Eddy Lures JD 60mm Depth Master " Green Candy ". Their listings say they dive 15 ft+, making them a practical choice for bass, trout, and similar predators holding deeper.
Cortland Line Company Ghost Tip 15 is the best option if you want a 15 ft clear intermediate tip for subsurface presentations in clear water.
