Guys, I need opinions from you, the most experienced and professional bass fishing sportsmen in the Earth! The thing is, recently in a Chinese fishing forum, a dude coaches me that "There is an universal lure(not only for bass) but I wont tell you what it is, if u have no idea what it is, u r the noob." He was so confident and proud although every single bass he got was from high density bass farm(b/c China does not have native black bass u know). In my opinion, choosing the lure according to various conditions should be a common sense right? What do u guys think? Is an universal lure that ppl can use in every conditions exists? Lots of thanks!
