Hi pilot4x4:
Don't have an X5-HA, so I can only answer the second part of your question.
I have two X5T standards: a black and a silver one. I have noticed that bits of the black have started to chip off, even though I rarely use this light (I don't EDC either of them). The silver one looks ok so far.
Having said that, I also have a silver X1, and in the process of trying to attach a keychain ring to the lanyard hole, I scratched up a portion of the tail cap. /ubbthreads/images/graemlins/frown.gif My ARCs and SureFires seem to have a much harder type III finish. I don't know if the X5s are type III or not though.
