What is it about the Evo version you want? Dropper post, flared bars or the tires?
There's not much difference so you can buy the aluminum and add the bits you want.
I like the wider tires. I often ride gravel pathways and our roads here on the Island are not in the best of shape, so wider tire would make the the ride more pleasant. I don't care about the droper seat post or the flared handle bars, so buying the aluminum model and changing the wheels and tire would make sense, money wise. I do like that blue colour, though.
