Wow! They are some amazing fatties! I'd also be intrigued to know whether you allowed them to congo from the beginning.
Only around 4 months in myself so still very much in a sectioning phase with a little core hardening taking place. My hair is stupidly straight, thin & fine though so it doesn't seem to want to congo.
Have not need to perform any separation at all thus far, in fact I have the opposite problem of getting them to congo naturally
Amazing dreadlocks! Mine are only gonna be five months old. Did they start out really thick like that or did they get that way over a long period of time? I want thick dreadlocks, I've even forced some little ones to combine.
