This is what I am doing atm and it seems to be working out really well for me. I still can’t decide if I prefer the Speedy Gadgets or the Power Wrench for that final slot in Tools, but I find that I use Toolkit less often than I thought I would (because things die too fast for me to get to that point anyway).
My Utils on this are Med Kit, Rifle Turret (for Surprise Shot only), Tool Kit & Utility Goggles. Supply Crate is the Elite I use.
Utility Goggles, Analyze, Surprise Shot & Throw Wrench are the standard SD spike and it never fails to wreck huge groups of NPCs.

I haven’t been using this a lot in dungeons yet but I am finding it is more than sufficient for solo PvE, DEs, PvP, WvW, and just about anything else I want to do. Solid all-around build.
Sigil of Fire on rifle, gear I am using now is an old set based around toughness and healing power for my KR stuff, I imagine that it will be even more beastly when I have proper gear to suit SD.
Edit: forgot to put in the image. -_-
Alright, what does SD mean tho?
