The major scales with its modes are pretty much the best for this. Well thats for me at least.. I noticed it seems to work everytime. Except sometimes i have to play in a different interval of the major scale, like in the sixth for some minor stuff.
Well anyways Im really happy with the results.

Whats next?

such as jazz
mostly because it is really hard to get down or figure out the trick
it forces you to think outside to box
