Current shoe: Adidas Predator

Possible buy: Nikes Mercurial Vapor V or Nikes Mercurial Vapor Superfly
I've always had a preference for Adidas shoes. I have tried out other makes ones but never got attached to them. I believe I'm a bit biased now towards Adidas, but these last couple of days Nike had got my attention and I'm curious in trying them out.
Here's the deal. I like the touch in my current Adidas Predators. The feel of the ball and the molding of the leather to my feet is really good and I like the shoes. I've always liked the soberness of the shoes in term of style, while Nike tries to show off more with fancy colours and top player names. Although my very high preference to Adidas, I feel like Nike has improved so much that I can't close my eyes for it anymore, while I don't really noticed that improvement for Adidas when comparing my current Predators to the Predator I bought several years ago.
The problem is I have a bit of a "fear" with regard to the "synthetic" material in the Nike shoes (I know they also have leather versions, but with respect to those shoes I think the difference between shifting between Adidas and Nike is smaller). I understand synthetic makes the shoe a lot lighter, but I'm afraid you have to give in too much with regard to the touch and feel of the ball. But I do would really like a lighter shoe.
But okay



Thanks for your help!
