This build uses two separate groups of weapons, 2 ERLL in the shoulders for long range hill poking and shooting from behind friendly mechs, and a waist high laser vomit group of 1 LPL + 4 mediums. (The srm 4 is thrown in to top off alpha strikes or as backup weapon while cooling.) The heat is fine as long as you use each group separately, and you can even alpha a couple times with all weapons in specific situations. The build requires lots of firing dicipline, but is very rewarding and flexible.
