Many fishermen from long-range and day-trip boats have always used conventional tackle over spinning gear, so the transition was easy. It'll be interesting to see if more swimbaiters start using spinning gear now that drag systems and gears have caught up to conventional reels, and in some cases, passed them.
Spinning gear is still perceived as amateurish among avid West Coast anglers because it doesn't take as much "feel" to make a cast.
Freshwater bass fishermen transition fairly easily to saltwater bass. There's no denying that these fresh- and saltwater species have similar feeding behaviors.
