Agreed on what @snakker said. Many of us started with very hairy lines (some of us still do so for sketching), but with practice, self study and time, you will naturally gain more confidence in doing those long stretches of lines. Especially since in digital you can just undo and retry as many times as necessary until you get that "perfect line".
Stabilization does help though, you can adjust is as needed until you feel comfortable with it.
