This is a build I've been testing in an idle moment - really needs doubling. Makes use of the 3 LL ghost heat changes. Good medium range firepower and works very well on Alpine Peaks... not looking forward to Terra Therma. Because you're keeping to medium range most of the time the XL doesn't seem much of an impediment. Its the classic peeper but with a couple of lonely backup medium lasers.
5/5, Have been using this more effectively than builds with ballistics. Metamechs also sees this as one of the best laser vomit builds. Might try to swap to a LE version, maybe by exchanging an LL for an ML. Doesn't use optimal ghost heat values, but freely using your side and center torso as shield helps with survivability greatly.
