Ashiko knob owner here. I've never used the Slammer so I can't speak to it. However, I've had the Ashiko for a couple of months and really enjoy the feel. I shift varying ways and don't have an issue with it at all. My hands aren't large and it isn't a problem. I recently installed the Kartboy short shifter and these work very well together. I highly recommend both! Oh, be sure to get the microfiber shifter cover. The knob does get warm after sitting in the sunlight for a while.
