I fish both, as I look for different things in various imitations and presentations.
Sometimes I want the extra thump and/or wag of a swim/boot-tail bait, such as Swimbaits like the Smokin' Shad, but other times I want a more-subdued, light vibration of a C-tail, most times on a 4"-4.5" straight, narrow body, like Ring-it genre plastics.
