Been experimenting with a DRG-1C. As far as dragons are concerned, I think it has a nice weapon spread and slot allocation. One ballistic in the right arm, one missile in the CT, two energy in both the left torso and left arm.

You need to go with an XL engine to really get some power out of it, but it has such a large CT anyways (and moves fast enough) that the XL issues are minimized. It makes for a good all energy weapon platform, mixed energy and ballistic, long ranged poke or close ranged harass, all based on your weapon configs. It also maneuvers pretty tightly, which is nice.
I am currently running it for mid ranged engagements with an ERPPC, Gauss Rifle, and three Medium Lasers, which is respectable no matter what mech it is, though it tends to get a mite hot. All that, and it still has almost maxed out armor and moves at 81 KPH, though the setup is still in a state of flux for me. Even had a lot of success with two PPC and two MedLas with an SRM6 at one point.
Up until running mine, I always put Dragons low on my target priority list, but they really can pack a whallup! Thankfully, I do not believe most people realize this, as I see them prioritizing CTFs, Hunchbacks, or Centurions over me.
