For much of the past year, i had been thinking to try something other Kamui soft.  But as much as i pound on it, it refuses to die.  It holds its shape well and doesn't need scuffing.  I think I've pounded it to at least a medium by now. I do shape it every two to three weeks with a dime radius Willard. The reshaping is minimal, serving more to scuff the surface.  It doesn't mushroom, and the side holds a deep, dark, hard shine burnish. 
So why change? I don't know. I've heard so much negative about it that i thought i would try something else and see. I hate it that it's overpriced and price controlled.  But wth. It works and continues to work.  30+ hours of harsh pounding between scuffs, including break speed stroke - ironing sessions, makes it a winner. 
Ironically, i had been thinking of trying an everest next. I think i just convinced myself that the Kamui is working well enough to keep.
