Goosander, I was undecided between the black and green as well. I like the green, it is a classic colour and in different light you get different shades of green, which I like. Good luck with your choice, I think both colours look great !
Swislon, I upgraded to the LX brakes as well, and while I don't have anything to compare them to, they stop very well indeed. I have a steep hill near me that I ride down almost every day at >55km/hr and at least once a week cars pull out of side streets in front of me, and my brakes stop me each time (great way to get the heart started in the morning !!).
You're right, I have the comfort bars, not the straight bars, and really, I don't think you are missing anything with not having inboard bar ends. I really like the cane creek ergo ones though.
