Biggie size it. Overly chubby trout are fat and lazy. In fact, so much so, they enjoy spending hours laying around doing nothing. As such, they tend to limit their feeding to only large meals. If your goal is landing the biggest fish of your career, stick to big fish baits, those physically larger than traditional offerings. While smaller baits incite more action, they also catch smaller fish on average. For really, really big fish, resolve yourself to sticking with big baits and resist the temptation to switch to smaller ones.
