Of course, usually when I face conditions not adequately handled by the arsenal, or when something becomes available that outperforms what I already use. Keep in mind that I've been doing this a long time, and I am always tinkering and modifying as conditions dictate, so it's fine tuned by evolution. I'm sure that if I moved to an area where the conditions and bodies of water were very different, I'd recalibrate and make more changes. As far as the latest and greatest lure de jeure? I keep an eye out for them and throw them when they intrigue me, but more times than not they are no better (and often no worse) than what I'm already using. I view lures as tools, they either work for the job at hand or they don't.
