There's this really great Carnauba wax and lanolin oil based conditioner called Urad that I've tested on multiple R&T leathers, it's really neutral, and will darken very little if at all, as it penetrates and dries as a wax does. When applied lightly(comes with a foam applicator), it dries clear and leaves a nice shine. Best thing i've found for an all in one conditioner that does not darken. Buy it in the "Neutral" color.
