This build tends to get pretty hot and you have to manage heat accordingly but it's pretty effective (at least for me), alpha is pretty good for tearing light's limbs. XL 320 engine is sweet spot between speed/heatsinks/ammo this Mech can carry (smaller engine - no crit slots for more heatsinks; bigger engine - crits left but no weight for aditional heatsinks) and speed is good substitute for fragile torsos that comes with XL. Although this build won't win sniper/long range competition it's damn effective in close combat and you still have 2 AC5s to dakka in distance. All in all, of all 4 variants Firebrand is my favorite now, due to better hardpoint placements.
Nice build. A good Alternative to the Riflejager build. I would downgrade Engine to have even more Ammo.
I have a very similar setup on my Firebrand now, however I go with 4 MLs ... which allows me to get rid of some heat sinks, upgrade my engine to a 340 and have 180 ammo and AMS. I do believe it looks something like this. It should be noted, that the sustained DPS of this build will never get below 6.66 ... unless you run out of ammo. This build is the bane of lights. It moves well for a heavy, it turns fast, its weapons cycle fast ... over all, very fun build.
Might be better to use something like TinyPic.com or one of the other online image hosts. Sky Drive stuff doesn't allow you to actually display the image in a tag.
This is a great build. Have been getting 1000+ damage more often that I ever have. Going to try to find something similar with UAC5s and the 340XL. Having all that mobility is too good to skip.
