Just an idea, pricey engine upgrade (5 mil) but damn is she fast for heavy medium.. Just worried about the lack of long range weapons...
ALWAYS min/max, ALWAYS! Take 2 points off armor and you get half a ton more to play with. XL355 is a weird engine rating, most people have XL350, maybe you can use that! Weighs less also! You can probably take less DHS too, it should be cool enough. Extra DHS can be added to the side torso if you have the space, helps crit-pad the engine. I reduce the engine to XL350 with the loss of only 1 kph, took out a DHS and 2 points of armor. With that I add AMS and 4 JJ. Should work much better. You don't have to add AMS though, you can get your extra DHS back and get a JJ.
