Is the lake clear or murky? Try using bright obnoxious colors for clear lakes and ponds or on sunny days and darker colors for muddy ones and cloudy days. Pike are solitary hunters and are extremely sight oriented. Look for lures with very erratic and fast wobble and again, crazy colors as this will help attract them. All of this will make your lure stand out. Maybe they were at a different depth level? Anything that rattles will help too. Finally what size pike are being caught? Pike can eat prey up to 1/3 their size and sometimes greater lengths so choose an appropriate size. They will almost always go for the bigger meal instead of ten smaller ones. Good luck and have fun catching them.
