However its very easy to clean the 14 way and to be honest you'd have to be a complete numpty to break it! all you're doing is cleaning of the old grease and dirt and re-lubing, you don't need to scrub the thing.
As for whether or not its worth it? the jury is still out on that one for me, I didn't really chop with my angel before and it is very consistant with a good paint barrel match, Mike put in an earlier thread that it stops any shoot down, sounds good to me!!
