Was surprised I didn't get at least one response, lol. Here I go jumping in blind, heh. So I figured I would share my experience so far so maybe others can learn some things.
1. It smells a bit like cat pee. I'm not even joking, lol. After Tokonole on the flesh side and Feibing's Leather Balm on the hair side it seemed to lessen the smell.
2. I found no need for oil. It really is buttery soft. I'm pretty sure buttero doesn't mean butter in Italian but it certainly does to me working with it.
3. I'm loving the leather balm as a top coat. It let's the buttery hand feel to still come through while leaving a nice sheen. It's not a cheapy looking shine either just a nice beautiful luster.
4. I'm foregoing an edge burnish and using rolled edges. It does burnish up beautifully but those rolled edges are turning out too beautiful.
I'll post other stuff if I come across any other peculiarities to it. If anyone else has any other things to share or thoughts on my process feel free to chime in.
