What colour are you looking for, I'm 6ft 1 and I use a Bulldog Kinetic carrier, yes it's a bit on the expensive side but for me it's worth it and fits perfectly, I use it in a M size but if you look on the carriers. For any carrier, Dutch the Hooligan is 6ft something, I think the same as you and he is using a carrier which has its front plate with 8 molle points wide which is going to be the bigger size. Can you provide links to the ones you are currently looking at please
