So, this build technically doesn't have to be on a Golden Boy (you could basically do the exact same thing with a KTO-19 or 20, sorta) but the other variants higher speed means you might as well use them as an SRM skirmisher. The fact that all three laser hardpoints are in the arms means you have good target tracking on light mechs. Having the SRM's in the center torso does mean that you have to open your missile pods to fire them, but you're a bit of a pseudo zombie since they'll have to have basically taken out your center torso to remove them. If you feel this isn't worth while, you can always stick the SRM's in the left arm so that you can always leave the missile doors closed and so that you'll have good target tracking with them as well. I've really liked this build so far, and feel like there are pretty small variations on it that are also very good (swap the LLasers for ERLLasers, swap the SRM4s for 4 SRM2s for higher DPS and tighter grouping, etc).
