I'm curious if my fellow boomkins have any tips or tricks they use to make the most of their starsurge procs. At present, I don't use any macros for starsurge. I try and stay on top of the procs as much as possible, but I still run into situations where I'm a bit slow in the heat of the moment. I'll be partway through a starfire cast and think, "Man, I should have cancelled this and starsurged instead."
I've seen people advocate the following macro to try and use those shootings stars procs that occur just before a starfire/wrath cast:
/castsequence Starfire
/cast Starsurge
I don't think I would use this on wrath because wrath is a much shorter cast, so there is less to loose from finishing it. Additionally, I prefer the control of getting that extra eclipsed cast at the end of solar. That being said, I've tried this macro on the dummies and it appears to add some separation between starfires. It's not much, but it would definitely add up during combat. To me, this seems to negate the worth of such a macro.

The other macro I've considered using is a stopcast macro on starsurge itself. Currently, when I get a starsurge and want to cancel a cast, I just move to cancel and then throw my starsurge. Do you folks use a stopcast macro like this? Or do you stick to moving to cancel casts?
On this topic, is there an agreed upon time to cancel casts to use starsurge? I generally cancel starfires if I can react to a proc in the first .5 seconds of the cast or so. If I have my meta up, I typically let the cast finish. I'm curious as to the latest point you would cancel a starfire cast in order to use starsurge?
I think my play is pretty solid, but this is a topic that I don't feel completely sure on. I would appreciate any insight you folks can provide!
