Dude, get whatever you want. If you want a plate carrier get one, try it out. If you don’t like it sell it on. I have various rigs ranging from PC’s to chest rigs. I prefer the PC in the morning as it’s usually cold and in the affernoon I switch to a chest rig as that’s when we play the speed games
As a starter chest rig look at the Viper VX it’s good value, decent and light. You can add bits to it as and when you feel like it.
The more you play then you will realise that running light is good. That’s why you’ll see people wearing belt rigs.
