Channel Skills?

Just thought of what build I want to play and it'll use the new channeling support gem with a channeling attack skill. Is there any good tech to use with channeling skills that I might not be thinking of?

Like I know reduced mana cost rings and infused channel gem but other then that I can't really think of anything with a channeling attack based build?

So yeah any cool channeling tech known?

cast while channeling builds are fun. But that's probably not what you are looking for.

I am not at all a fan of channelling skills (except Cyclone), because of the need to stand still for extended periods of time. I'm sure its something that can be gotten used to though.
