I haven't made this mech yet so it is still theory craft, but I am excited to try it out. Things I don't like: it is sloooow for a BM. The 330 doesn't leave a whole lot of top end, but the big alpha should melt most small mechs in one shot, leave the mediums critical, and the high heat capacity should allow for at least two alphas before any kind of heat issues. Thoughts?
An alternative to get around the LLas ghost heat and a larger engine: http://mwo.smurfy-net.de/mechlab#i=119&l=96273147e0d738eb07451c645eb4d2b9b790fd00
