A couple of weeks ago I replaced the white, red and blue Double LEDs that are in all the GI on our Wolverine and put in Cointaker white, red and blue retros (plus I put in a few that are frosteds where they are in view). Overall I really like the machine with the retros better, just gives it a nicer look. I find the Double LEDs just don't throw out as much overall light as compared to the retros.
Just thought I'd post this for anyone who might be looking to brighten up their Xmen LE a little bit. To me I like the change, it's worth it.
