I'm a 50% clencher 50% holder, I like taking my softy bits on and off all the time and feeling the natural surface of the stem. This doesn't quite work for me, I just try getting stems that are not real wide and if they are, not real thick. I love cobs because you can replace the stems for 50 cents or $8 for a freehand without sending the pipe in. For better briars with stems that trigger gag reflex with the pipe softy, I am probabley just going to either be a holder or to get an extra stem or two made for clenching, and keep the original stem safe.
