I have a 6P that came with the standard Z41 twisty. I purchased a replacement clickie from DX for <$4, it works fine. Now I have a Z41 just sitting on the shelf. The Z41 has better knurling and higher quality overall that is easy to see. I just can't bring myself to pay $40 for a surefire clickie. Is it possible get a clickie switch from DX or wherever and convert the Z41 to a clicke?
