Below is a breakdown of every loadout I have had since hitting 6.0+ Fence rep. Every Headset, Helmet, Armor, Weapon, Rig, and Backpack that I spawned equipped with, as well as some additional interesting/valuable items I had in my backpacks. I should go back and tally up the grenades later, I probably had at least one grenade ~60% of the time, and sometimes 2.
|TK FAST MT||8|
|TV-106 + TV-109||4|
|Labs Access Cards||10|
|Folder With Intelligence||1|
Loadouts definitely get better on average with higher rep, and you seemingly never (or at least incredibly rarely) spawn with a pistol at maximum rep. You still rarely have a relevant helmet, you usually have some amount of armor, and having a helmet is a coinflip.
Keycards have been ~1/9 raids for me. Stacks of roubles are ~1/5 raids and can be 35,40,45, or 50k.
