Interesting, I prefer the broken record stutter. I changed my type of stutter from the blocking type to the broken record time (no sound to m-m-m-m-m-m) by forcing myself to make some sort of sound every time I blocked. I prefer this because this way at least people know what’s going on - I have a speech impediment. With the blocking type, people just get confused why I stopped talking. If you really want to change your stutter type to the blocking time, I guess you can just be silent until you “feel” the word is ready to come out.
