Cool I went ahead and selected Plastic Worm. My PB Largemouth was caught on a 3" Senko. Which after all is said and done, is really just a stout and fat plastic worm I keep my Senkos in the same box as my worms and generally fish them with the same rigs anyway.
Interesting about the spinnerbaits. I use them frequently, and if told to catch as many bass as possible in one hour with one bait, I'd select a spinnerbait (or depending on cover, an Inline spinner).
But if I was told to catch a large bass with one bait in one hour, I'd go with a Senko or regular Plastic Worm. Just seems to work out for me that way with those lures.
