I'm far from being a good player and my ping is horrible, but the build is solid enough that it doesn't feel like I am piloting something that is too heavy. I can get behind cover faster and hide from LRMs and I can get to other locations on the map a little quicker than usual. Once you finish your elite efficiencies, this should be going over 60 kph.
The 4 Medium Lasers and Gauss Rifle are pretty standard and you also have your AMS. I chose to put 2 Streak SRM2s because I have problems hitting light mechs with my latency. They are still good to have and I chuck them even at other assault mechs for extra punch.
Endo Steel and DHS round it off. If you don't put DHS, 18 heat sinks won't be enough to give you decent DPS. Heat efficiency might go down if PGI decides to nerf engine DHS (currently 2.0 in engine instead of 1.4).
Armor is maxed in all places except the legs.
Anyway, here's the build:

Adding repair bill (after being cored) for sake of reference about its maintenance:

Feedback is also welcome. I already moved the AMS ammo to the leg and added case to the right torso for the gauss rifle as recommended, but I haven't updated the image yet.
