The engine, ammo, jj, and heatsinks can be tweaked a bit to pilot preference. I have found this to be an extremely agile loadout at a variety of ranges.
Using the XL325 will allow you to add an extra heatsink as well as use engine slots. Also add that last JJ, and max out your leg armor. You may not be a fan of XL engines but I use one in my 732 and I regularly run 400-800 damage runs with it.
