Thanks. I have another Arca on the way - in dark navy / matte croc. Love the Arca!
My two cents worth is that you should get a color from Corthay OTHER THAN black. One of Corthay's strengths is its otherworldly coloring and patination - and you miss a lot of that if the base is black calf.
Colors with lots of black in it - like lie de vin or aubergine or navy - via patination/burnishing look black anyway at first glance or in dark lighting!
Oh. Forgot I have Vendomes in...
