trailrat,
Ive cought them with a flash or a flashlight i prfer the flash so you can go straight to fishing and not have to worry about the glow for a longer amount of time. also i use yarn so that i can apply shrimp oil and so that the yarn tangles into the teeth and gives you more time to set the hook. heavyer line is a bonus also. personaly i use two orange glowsballs together, i fell it looks like a nucular shrimp. it has worked great for me. good luck
