This build have a different way of surviving from the tank build, instead of have 200-ish armor, this build only have around 130 armor but having 45% dodge chance (perk deck included). While sprinting your dodge chance increased by 10% meaning you have 55% chance to dodge every incoming damage. It sound pretty good, however, it requires more skills from the player.
In order to gain the highest dodge chance, high concealment weapon is required
The Dodge chance is directly affected by your detection risk level
And here is the relationship between (for this sprinter build only)
It will further decrease for higher detection risk level down to 35%
In order to maximize your survivability, you should keep your detection risk level below 19
Akimbo pistols
Suggestions: Mid-tier damage akimbos

• Akimbo interceptor 45 pistols
  
• Akimbo chimano custom pistols
  
• Akimbo crosskill pistols

Reason not using High-tier damage akimbos (e.g. deagle): you do too much damage which are wasteful on ammo

And of course use whatever you like, but stick with pistols!
