The simple reason that bass fisherman use baitcasters is for control. A baitcaster provides the control bass fishermen require for accurate casts in challenging conditions and other obstructions.  The other control necessary for bass fishing is how fast a surface lure can cross the water. Bass are aggressive but finicky. If a bait designed to look like a swimming mouse is too fast, they’ll ignore it. If one that is supposed to mimic a swimming frog moves unnaturally, they’ll ignore that too. But, if the lure moves at a speed, and in a pattern the bass is attuned to, they’ll hit it like a freight train.  That’s why bass fishermen prefer the baitcaster.
