What's the difference between double-bladed lightsabers and common lightsaba's?

Besides the number of total blades?

Single
Damage Type: Lightsaber
Maximum Hits: 5
Minimum Damage: 15
Maximum Damage: 22
Minimum Range: 0
Maximum Range: 0

Double
Damage Type: Lightsaber
Maximum Hits: 10
Minimum Damage: 8
Maximum Damage: 11
Minimum Range: 0
Maximum Range: 1

As can be seen from the numbers RIGHT off the rules, doubles offer more hits, but less damage per hit.

The double also has a maximum range of 1.
