Confidence is key!
Before I saw a bass angler catch bass after bass on a skirted & trailer in a tournament, I had no reason to think such an unnatural looking lure could catch fish. The next day I tried one with a pork frog trailer and nothing - at first. But having left the lure in the water while having lunch, I forgot it was there and turned on the trolling motor.
As soon as the boat started moving, the rod bent as if the lure was stuck on a rock but turned out to be a 2 lb bass. That day I caught over 6 bass - most in the 1.5 - 2.5 lb range and now will always have one rigged when fishing for bass.
Another thing: I never thought a trailer could be anything but a real pork trailer - at least until I tried a soft plastic one and then caught the same amount of bass - two over 7 lbs.! I switched to using soft plastic trailers in different designs long before Uncle Josh went out of business and now pour my own.
