This was the first build a friend of mine used after purchasing the Grid Iron right after the servers went back up. I liked the idea, but take a slightly different approach by using ERLLas. Standard LLas are probably better as soon it gets into brawling, though. Nevertheless, here's my variant. Comparing those two I'd remove 1 DHS from your build to add that second ton of SRM Ammo. And your leg armor... don't know if I'd like it that way. Replacing the ERLLas with standard versions bumps the cooling efficiency to 47%.
