Don't get f50.6s, they're prone to breaking at the sole and studs. Nice idea but badly designed. It's a bitch cause one of my teamates had to do something to the studs before a game and half of each stud broke right off so he couldn't take out the other half still stuck in the shoe. He ended up playing with missing studs. Not so good. Many pros don't even wear them because of their problems, and they get em for free. Instead, they use the same upper of the shoe, except with non-interchangeable studs. Not sure if the new f50.7 version fixed this though.
For the guy who wanted some insane cleats check out puma v1.06s. They have one in this obnoxious gold/blue colorway and come in a lot of other colors. They don't look very durable but I think they're the lightest out there. I've heard they fit like socks and have really good touch.
Or try lotto zhero gravity's. If they fit your foot well, they would be killer. They got no laces, and super light.
I personally wear vapor k's. great touch, light, and fit my foot so well and tight.
