I use 232 HP / 160 Def / 16 SpA / 4 SpD / 96 Spe with a Modest nature. The 16 SpA hits a jump point. I find that Togekiss doesn't really need much SpA besides a Modest nature because it ohkos pretty much every offensive threat at +2 anyway (it's stronger than Timid NP Mew, for reference) and flinch-rapes every defensive threat. The defensive investment is super useful for taking powerful physical hits - to give you an idea of its tankiness, it always survives CB Weavile's Ice Punch at full health, takes less than 50% from Scarfgon's Stone Edge, and always survives Impish Rhyperior's Stone Edge (which lets you recover from a failed flinch or those insanely depressing Air Slash misses).
Druddigon's purpose in life is to 2hko the metagame with CB Outrage while being bulky enough to avoid getting revenged by anything besides very strong SE attacks. For reference, it has around a 50% chance of surviving LO Kingdra's Dragon Pulse if it's at full health.
Drapion is a great bulky SD sweeper. It caught my eye because it's kind of like Bulky NP Togekiss, except with better typing to compensate for lack of Serene Grace. It's also really fun trolling Gligar with ice fang.
