TBH I would go afterburner vs MWD. Depending on how much you want to spend you can get up to around 700m/s. Slower than the MWD but you can more easily sig tank, and you are still getting almost 60KM range with javelins.
It also allows you to drop all your cap mods except 1 CCC rig and remain cap stable. That gives you 2 more mids for either tank or damage as well as one more rig slot.
