I just got done building another one with a 360 thumbstick. So far I have made 3 and I did something different on each one. I haven't decided what the best method is yet. I still have a couple more to make for friends so I hopefully I will decide on a set method by the time I finish those.
Anthony, I have lots of both thumbsticks so whichever you want is fine with me. They all work the same, it is really just a matter of personal preference. If you only are going to use it for driving games then I recommend the stiffer spring in the brake trigger. If you want to use it for all games then you may not want the stiffer spring.
I was playing NBA 2k2 last night and having just one trigger stiffer then the other was making the free throw shots harder. I can't really think of any other game it might effect like that but it did throw me off on that one. I lost a game on my season by 2 points and I missed at least 10 free throws that game.
I have so many controllers right now I can just make a complete one for you. That way if you want to make any more you can just take that one apart and see how I did it. There really is nothing to them inside.
Let me know what you want and I will build it in the next day or so. I can just mail it to you and once you get it just mail me back a normal DC controller and we can call it even.
