I've tried most of the available finishes, including hot tank bluing, chrome, nickel, DLC, PVD, etc. And basically settled on H&M Black Nitride as my top choice. It's great for durability, super fast turn around, and very affordable. I recently had a complete DLC refinish done on a SV that I put a new top end on and seriously regret it. Could have had a better finish from H&M at probably 1/8 of the cost.
