Ideally all of the LRM's should have the + (stb. damage) modifier. This loadout is serviceable well into mid game, or until you posses a 'mech better suited to the role. The Shadow Hawk SHD-2H is fast and well armored allowing you to keep the enemy at range while launching stability affecting volleys into their formation, forcing them to back off and entrench or risk falling over. Pair this with a fast melee 'mech or a PPC sniper and you can salvage most things you come into contact with.
* Better loadout then above is using 2 LRM15 instead of LRM10+LRM5. This reduces the heat by 3 but same dmg. Putting the LRM ammo in the center torso is dump idea since you can get ammo explosion in the one place you don't want it! Put the ammo in the legs instead and the jump jets should of course be in center torso. You want to use your jump jets when you got one of your legs destroyed I presume?
