i bought these as a lark. i was just curious to the multicurve and wanted to check them out. all my other plates have the basic curve. so i wanted to see if these were as good as they seem. after watching every video most likely, i took the bait. and man, i am glad i did. i will admit that with a trauma pad you cannot tell much of a difference from these and a single curve. however with prolonged wear or if you wear your carrier really tight to your boddy you will certainly notice a difference. even tho i bought these simply to answer a question, and had no desire on upgrading my kit, but i have since made these my primary plates. i keep these in my main gear and ive moved my spartan armor into my backup p.c. i HIGHLY recommend these plates as well as watching the videos on youtube. you will not find a single negative or derogatory video regarding these plates.
