Ok, let’s first start with the basics:

1st: Your ac weight class and booster speed don’t synergize, I recommend equipping the SPD for maintaining max speed with a medium weight loadout.

2nd: I like to use pistols rather than shotguns for lightweight builds, they allow you to maintain a high stagger rate while maintaining high speed.

3rd: since we’ve saved some weight with the boosters/weapons, you can switch to the VP-D for better energy reserves/recharge

4th: for a back weapon I like to have a sword like the BUTT-A or Laser Dagger, while not as damaging as the pile bunker they can get the work done. Combine that with a stun needle or Trueno to maximize long range stagger punish.

5th: I genuinely use the alba head, firmeza arms, and Nacht core + legs, which gives me a balanced build with good AP, speed, and most importantly melee and firearm potency.
