Drop shot spinnerbait!

Ok the other day i went fishing in my pond, i was fishing the dam were the gravel is an i had a minnow rigged for a drop shot. About an hour later i hadnt caught anything, then i decided to try something i had never herd of. a drop shot rigged spinnerbait. i uesed a willow leaf blade spinner, i rigged it drop shot, casted. an boom a 4 pounder. next 2 cast nothing then on the 4th boom a 3 pounder. i was fishing this spinner bait off the gravel on the dam. an that place is deep. that day total i caught 7 bass all over 3 pounds. what is up with this pattern. i had never thought of trying it or even herd of it. for some reason this worked? if anybody trys it let me know what happened? By the way i cant wait for the spawn, i got a few tricks up my sleeve to try:D
