Reply to What scales for what genre?

Heya, I got myself into producing some time ago and I've got the technical basics down. Or atleast down enough that my next barrier is music theorie. And that is also my question.

I listen to all sorts of house, from electro and progressive to tech and nu disco.
Anyways, when I try to produce I'm unsure what scale I should use. And I know there isn't a set scale for every genre, but for example Progressive House/Dance gives that epic feeling while tech house gives something more funky/groovy.

My question is what kind of scales are commonly used in each (sub)genre?
And wich are used to give that 'epic' feeling?
