...unless the water is very clear and you're fishing very shallow, it doesn't matter one bit what your bobber looks like...I once saw a little girl pull in a 2-lb shellcracker on a "Spongebob Squarepants" plastic bobber...seriously, though, your bobber needs to present as little resistance as possible when the fish takes the bait...that's why I prefer torpedo-shaped floats...steer away from the round plastic floats or other "doo-dads" like lighted bobbers...that kinda stuff is designed to catch fishermen, not fish...lol...
