I'm sure someone will speak up besides me but......
Just watch for buildup. Some get it some don't. You're already using what you need to get those products out.
Now if you had to give up one I'd give up that Garnier Fructis. I love the product but if I had to choose between using it or OneC I'd keep the OneC. It has the cone farther down the list therefore less of it and it's a great detangler and a good conditioner.
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
