I've run this build quite alot, and love it to bits. It has speed, range, and good hitting power. It's a bit better than the Gauss or AC20 build if you can hit them from range. The MG's and ML come into play once you can tear the armor of the mech, and crit those internals. for weapon groups, I run this 1. Uac5 2. All med lasers 3. All Mg's 4. Chain Uac5 5. chain ML
Speed and Heat are decent in the mech and the mix of ranges is nice, but, the MGs give me pause. Hunchies that always look at their targets tend to be dead hunchies - twisting away and offering the arms critical to surviving a long fight. Using MG means that your CT is always available... problem for me.
