And the head caps on the DDs are a PAIN to get off. You have to MOD the head cap by cutting off a small section around the inside of the cap, if you don't, it will be a major pain to get the head cap on and off. You have to use a butter knife or a utensil to pry it off, it is really stuck hard in there. There is a post about how to do this somewhere on DOA. XD I'd have to find it again. I did it to both my DDs.
