I think we go through phases of liking a certain metal color. I was all about silver tone metal and then loved everything gold, went back to wanting to wear silver tone metal and now it is a combination of both depending on my outfit. If it were me, I would choose a different size but if the size medium is your preferred size and suits your frame then you should stick to that size.
Just for reference, I have a black medium CF in gold hdw, black mini in gold hardware and a black mini in silver hardware, black mini-woc in silver hdw and black new style mini-woc in gold hdw and I don't think it is too much. I branched out to color in the small CF size and minis.
