Thread: Salm Rock/Old Rock Coti's vs Other vintage Coticules

So i've began using Coticules exclusively on my blades. At least for the moment my Thuri's are getting a rest while I master my coti's. I have been getting great shaves off a vintage Pike No. 1 Fine grade 7" coti and a barber's Special grade coti 4"x2". I'm dying to try a Salm Rock or Old Rock coti but haven't gotten my hands on one yet. How would they compare to what I'm currently using? I don't have a pic of the pike at the moment but I've attached a pic of the barber's special.
