^^ couple of things about leathers:
My natural CXL boots basically turned brown after the first treatment of CXL, and have darkened ever since. Now, it's a cool brown, but just keep in mind that that won't keep that natural look for long.
In my experience CXL is quite a bit softer than HH, and I think (though some will argue) less durable.
How did you treat the natural CXL that it turned brown after the first application?
I agree with your opinion of CXL vs HH though. CXL is very soft and not extremely tough, although it will take a lot of beating
