Dacron's elastic properties are more forgiving of an abrupt opening than other line types. That is why Dacron is a popular choice for students, camera flyers, or anyone else who wants to minimize the results of a hard opening and is not overly concerned with the addition of more bulk. Dacron is the largest of the line choices and is not a good choice for someone looking to minimize drag or pack volume.
Pros - most elasticity of PD lines
Cons - Bulky and abrades easily
