It really depends which sort of base you buy, there is the SG, FG, and AG. The Vapors would cost the most but if you are going to get the Nike Mercurial Vapor IX FG Orange cost around 159.99 Euros but for Vapor AG its also 159.99 Euros but for the SG, it cost around 169.99 Euros.
quite easily and if you buy t90 or talaria which is cheaper version you get better performance and quality
Absolutely not, i have a pair of the black and yellow boots and they are good, but not worth the amount of cash. You can buy cleats that are just as light as them for a fraction of the price.
I have mercurial vapor 6's and they use synthetic. I find synthetic less comfortable and harder to break in. The thing about mercurials is that they are very light and there is good touch, so it really depends on your taste. If you are playing competitive, I recommend the mercurial superfly 2. Hope this helps!
