The cream is sort of to make the hair more manageable and keep the oil from coming off/being oily from what I can tell.
If you are only gonna LOC twice a week then maybe use your knot today on days you cowash and don't LOC? I know it doesn't really make sense to cowash without LOCing but hey lol. Or use it as your liquid to detangle. Then oil and cream. But my experience with knot today is that it doesn't mix well with other products. It gave me build up and crust when I did.
My favorite creams to use are giovanni leave in conditioner or shea moisture curl enhancing smoothie. I use water based creams during the spring and summer and for fall and winter for extra protection i use oil based creams, that being whipped shea butter.
