Well I'm kind of glad it's been dark when I've gotten home all week this week, because I didn't have to try to get used to the stock trigger

The installation was pretty straight forward, the only thing that I got hung up on was the lever. I reassembled and the gun wouldn't cock (tension but no "click"). The PDF didn't depict/mention this part, but after a few searches here and a revisit to Charlie's site, I figured out what I was doing wrong:
"Be sure as you slide the trigger blade up and into position that the lever, the long piece of metal above the trigger blade, is riding in the slot (C) on the top of the trigger blade and not riding up on the edge of it."
I just slid a small screw driver in the pivot pin hole as I was inserting the trigger, ensuring that the metal lever slid up in the channel in the trigger.
I think the best part of this mod is how easy it is to install, bolt on and go with no modification of existing trigger components. That means that you can easily remove the trigger and put the stock one back on. From using it today though, I don't know why anyone would ever want to do that.. :p
The only way I was getting decently accurate shots before was to just pull fast (on the stock trigger - this is shooting in the dark mind you).. The new trigger incredibly reduced the amount of pull required, and you can distinctively feel the stages now as well. I got a few hours of straight shooting in today, and I didn't really mess with the stage 2 adjustment, but the stage 1 I opted to shorten just a bit. I just about have my scope zeroed ( I was getting ok 1-2" grouping at ~50yds without benching), and it doesn't seem to be creeping at all (even without loctite, etc). I realize that it probably will over time though, so I'm going to probably pick some up tomorrow and re-mount it (another excuse to play with it for a few hours lol).
So the stage 2 adjustment, I'm a little clueless here, what does it actually adjust in relation to the second stage (shorter/longer pull, or ?).. At the moment I'm pretty satisfied with the performance and feel, but I would appreciate a better understanding of "creep".
Thanks for the help

So
