Conventional reels without level winds cast farther and are more preferred by pro anglers. However, some people have a hard time using them; hence opt for level wind conventional reels. This is how you use conventional reels without level winds. Without the level wind, anglers guide the line back and forth with their thumb. Spool up the reel with a  smooth, finished braid. Use reels with a narrower spool as it makes it easier to spool. Using your thumb will seem difficult at first, but it becomes like second nature after you are used. If the line wears off your hand, you can use gloves. Cut off the thumb on the glove that goes to your casting hand. You must ensure the glove still helps maintain sensitivity.
