I tested alot with TBT-7K Specs and I think the following is the only workable:
2 med Laser
2 Streaks
AC/10 or LBX10 (AC5 if Std Engine and FerroFib Armor - because of lacking slots)
AMS
Engine according to your own demands. Means, whether you need BAP or not and your Ammunition consumption. I tryed XL300, XL280 (weights same as 275XL, so take this) and Std275. That brings your speed to 100 km/h +/- a bit.
You dont need extra Heatsinks, but DHS Upgrade (10 DHS from Engine is enough). If you are to hot, just stop shooting med Lasers.
My TBT-7K is fully armored, but if you lack in weight you can reduce some armor of the left arm (right side in mech lab), since there is nothing installed. But be aware, that you will shortly have nothing to protect your side torso (important, if you use XL Engine).
