I have a natural combo Les Latneuses, the yellow Coti side with a hybrid side.
The hybrid side doesn't do it for me, it's less sharp and less smooth than my Coti side.
But the Les lat Coti side is very very good for me. I always finish on oil (I used some fine machine oil, mineral oil on this one), and it gives me a very very keen edge but so so smooth.

I know on the old Coti forum some ppl went crazy for the hybrid side, originally these hybrid sides were looked at as defects by the manufacturer, and I understand why, they contain quartz and are not a real Coticule. I finished 2 razors on the Coti side, and one on the hybrid.

I didn't like my hybrid side for finishing, my Coti side however is a very superior finisher, very sharp, very smooth very friendly on my skin.
