Use whatever kind of line you are comfortable with, but try not to make them too short and choppy. As you can see, I've used a combination of short and long lines, although I always aim for a fairly long and flowing line. Don't worry about erasing mistakes at this stage - just redraw the line you want or ignore it and keep going. That's one of the advantages of drawing a natural object like fruit - nobody will know if it's accurate or not!
