"My sweet tits is it cold!" edition: http://mwo.smurfy-net.de/mechlab#i=40&l=0e3f65d0c0c40653f85dd046b65c351c4f009b0b Essentially created in response to the PPC nerf, this build aims to allow jump sniping while remaining as cool as possible for brawls. These builds have a 60% and 71% heat efficiency respectively when firing only the PPCs. It is almost impossible to be cooler without going into a heavier weight class. You can easily add an AMS into the second build. Just take out a HS and some armor. I didn't include it just to get it as cool as possible. My rationale is that at sniping distance, it'll be pretty easy to duck under LRM fire.
I really like the first build, though I would drop 2 JJs and replace them with heatsinks since you have the free slots. You could also drop the AMS+ammo and replace it with another heatsink and full armor for 49% cooling efficiency. For the second build, if you went with a STD275 engine, you could even cram in one more heatsink, though you have to lose all but one of your JJs and a ton of armor to do so.
Sass, you literally just described the second build with 2 MLas instead of one MPLas Chattah I'm currently testing this out right now. The speed makes it pretty easy to keep out of that 90m range, though I'll have to do more testing to give a final verdict
Not really. I think dropping to the STD250 engine in your second build is too much of a sacrifice in speed. I would personally prefer to lose some jumping ability instead, though I would likely keep the AMS.
I've updated the second build with an XL engine. Speed seems to be imperative with this build (the 90m minimum range) so a smaller STD really isn't an option. An XL, however, is totally feasible.
