These Remo Symmetry Fiberskyn conga heads feel more like natural hide than most synthetic skins and have a little of that warmth that you get from hide, but you get a massive powerful note that really projects well. I use these on fibreglass LPs for gigging. I hadn't used the symmetry heads before and had actually been looking for tucked heads, being a bit of a traditionalist, but couldn't find any. These are actually better, I love the feel and sound and they are tidier without the tuck. It looks exactly the same skin material. The only downside I would say about fibreskins is I have found the top layer of the skin (the hide looking and feeling finish bit) becomes detached from the main playing part of the head over time which is why I was replacing my previous ones.
