Just a word of warning for those who might use mink oil: I don't know about other brands but Kiwi brand mink oil also contains silicone. From what I have heard here on BF and from the guys at the leather store, this chemical is not something you want to put on leather.

Just read the lable of any product you use.

And Rowan, the tush is feeling fine. The saddle has slightly more flex overall than when I first installed it, but still crazy firm. Visually, there is not much difference, but I can feel a bit more give under my left butt cheek. I guess I put more pressure there. It's not uncomfortable. Just something I noticed.
