Fat boys look silly in plate carriers. PCs tend to be no more than 8molle columns wide (=12") and on someone with a belly circumference exceeding 50" this looks like a thong on a beach ball. Without a cummerbund it also has limited capabilities, and with a huge belly equator to traverse the thin cummerbund bands tend to loose support and dip. Armor vests tend to look better, but be careful not to look like the hero from the internet.
The nice thing that bigger guys have going for them is that they can wear big chest rigs and can make good use out of them because they have a wider front platform than us skinny guys who can maybe fit 3 mags flat across before mags wrap around our sides. I would suggest that you start with a cheap platform to test out nice pouches before you drop coin on a armor vest. The vests are only as good as the pouches you put on them.
About armor in vests for airsoft... unless you are training and have real plates or real weight, don't bother, (or unless you have a ciras because the back portion tends to bunch if there is no hard armor to support the structure) it will only make you hotter in summer games, and restrict your movement. If you wear gear to be cool, you are doing it wrong.
for clarification... too all and axisofoil
There are two types of CIRAS vests, land and maritime. I can see how the maritime version could have some of the velcro get snagged while crawling backward through bushes, however that should not discourage you from buying it, it is good kit. The land version, properly worn would not have such a problem.
If you are tallking about armor vests like the BAE carrier, CIRAS, IOTV, Spartan II, etc... they are vests that hold both soft and hard armor. PCs are just for plates and maybe some specifically cut backings.
"operator cut" is an outdated and meaningless term, you need to go back to school and learn about BALCS cut soft armor vs. LE type, and different types of armor plates. If the term esapi is new to you then speaking about armor is wayy out of your lane.
Also, I would like to see a picture of your armor configuration in your chest rig, perhaps in a different thread though.
