http://www.torhead.com/skill-calc#700bZrI0bRoZGbbkrMhz.1 this spec leaves two points, which you can either use in Reopen Wounds or Arsonist.
Sab Charge with this spec basically becomes a 1 energy damage ability.
The spec gives you a minimum of three dots (Shrap, Vital & Shock) and four with Flyby. Wounding Shots is a must have in this type of spec, the damage output is too much not too.
Cool Head is reduced to 90 seconds via Fighting Spirit, no need for Sabotage unless your going for a 31 Sab build.
Energy management is critical for this spec, proper use of Cool Head, Illegal Mods (if you have the set bonus) and Flurry of Bolts is required.
The two points in SS for Steady Shots is a must have, 6% increase in Speed Shot and Wounding Shot is nice.
