I own the infinite stingray PB (phantom brass), Infinite red copper, and HCigar Black copper...allwork well..but I like the switch on my infinite better when I had them.
But for styling...I like Black copper...easy to clean, hits decent..but I have to just hit just right to fire..maybe the Infinite switch is better on the black copper...I know few modders here on ECF fix these issues so I'm sure they will chime in.
