The shadowhawk build for polite snipers. Designed for long/mid range engagement, I'm still testing the thing but it works well so far. Just stay away from regular brawl. Gauss + XL engine is never good, but I haven't that much problem with it. STD is always an option, even with CASE to protect the engine from explosion, but it forces you to downgrade to 200STD (64kph with tweak) or less. As expected heat-efficiency is very good, particularly if you're harassing and thus not firing at full rate. Careful new players, the gauss requires some practice to get used to its unique trigger mechanism. Though it's a fun and rewarding play-style once you mastered it. PS: works great on the SHD-5M variant too, with both lasers on the same arm.
