OH,.. Contraire!
The more you learn about bass fishing the more you "will" need.
More lures, more rods, more line, more tackle boxes, more boats (as in ,... puddle jumper, canoe, bass boat, kayak, etc:). and yes ,.even more knowledge,.....The "needs"???? are almost endless. Ive been bass fishing for 50 years, and im still learning, as new techniques evolve, and still buying, to apply those new techniques.
Although some like the senko, and ned rig Ive yet to jump in on, Im sure I'll get to them some day.,..Its more like I have older techniques that do much the same.
