Personally, prior 3.0, the only smn and sch macros I've been using are

/ac "Eye for an Eye" <tt>
/ac "Eye for an Eye" <t>

Smn 3.0, I've made a /hotbar change macro on a key to toggle between 2 hotbars, one for normal stance, one for dreadwyre trance.
I was combing the hotbar change macro with the actual dreadwyre trance and deathflare, but I can't spam the key or queue the skills if they are macro, therefore I've made separate hotbar change macro. The toggle works much better now.

I have this macro on hotbar 1, to toggle to hotbar 4, which has the ruin3 replacing ruin1 and deathflare replacing dreadwyre trance.
/hotbar change 4
Once the hotbar is changed to 4, I have this macro
/hotbar change 1
on the same key, therefore pressing the button again will toggle back to hotbar 1.
I have this button bound to a mouse button so it is very quick and easy to toggle between the hotbars.

As for sch, I personally use <mo> macro but I know a lot of people detest this.
