After testing 6 and 4 PPCs and ERPPCs I stick on this new setup I am enjoying a lot. That is my Crippler Mech, heavy armored, fast for an Assault, relatively good heat efficiency and effective at all ranges below 900 mts. The best is engage at 500 range mts, if you are skilled enough you can pin point arms and legs for Crippling your enemy. At short range it is also decent, as you can sustain a lot of punishment and pin point the head for a fast kill. The 300 STD ENGINE is pretty good providing good speed and maximum heat sink capabilities. If you want to improve the heat efficiency you can drop the Endo Steel and add 2 doubles, but you will to decrease the armor, which can be something trick. For grouping I use 3 groups: Group 1 - Left weapons Group 2 - Right weapons Group 3 - All arm weapons to shot mechs above or below. -23 -23 1-3 1-3 1-- -2- I hope you Enjoy.
