I'm working toward this: http://www.torhead.com/skill-calc#301uMhrdMboZ0MZfhMrzh.1
Unfortunately, if you're going anywhere in to the Pyro tree, you are required to use at least 3 points that buff Combustible Gas Cylinder, so those are wasted points if you intend on using Ion Gas Cylinder (and buffing that in ST).
Many of the other builds linked in this thread also don't get the 50% snare on Cylinder proc from ST or Pyro lines. I'm not sure why you would neglect these talents in PVP. The alternative seems to be regaining a small amount of heat when you are incapacitated (too situational for such a small gain to be useful IMO), or 1 point in ST.
I plan on respecing a few times at 50 to try out different things, this is just the build I'm going for while leveling/pvp.
That actually sounds really good, I wish charge wasn't part of the ST tree, It seems like that's the main reason to go down ST for PVP builds.
