Adjust your trigger screws for pull length (see the "manuals" section at angel-owners.com) and if you want light, forget buying a spring kit. Go get a nice "click" pen (one that has a light "click" to it) take the spring out, cut it to size, and put it in. I've got pen springs in both my angels and the pulls are shorter and lighter than my mousclick. As has been mentioned, angel-owners is a good resource for this kinda stuff (but if you go there, don't just start a new thread asking about your problem, because chances are, your question has already been answered. Use the search function, or the mods tend to get mad at you)
