I, as well as many others I fish with, have caught numerous 8 and 9 pound largemouths on Senkos, lizards(various brands),Carolina rigs (using Senkos even!) crankbaits, top water lures -- to name a few. Some have been caught on steep/deep bluffs, some on shallow banks. This all leads to the conclusion that you have probably not caught as many, or as big, fish as those using Senkos have caught.
And, you never will as long as you retain such a narrow minded opinion.
I do agree that you certainly can't teach anyone anything about a Senko if you don't know anything about it yourself.
Good luck, you will need it.
