I have both, but have not found the need to use the laser yet. I only need the matts for AFMU refils and you can get that easily off a surface of a planet.
If i had known that before leaving EA then i would of ditched the laser. Also loaded up 2 modules of heat sinks for the "just in case" moment. Not realising you cant restock with matts alone, i wish i never had them too.
