Most Obnoxious Dual Lane?

So I was watching a dota cinema video today where synderen and sunsfan were doing a dual lane with Viper and Venomancer and it got me thinking about really cancerous dual lanes. What do you guys think is the most obnoxious dual lane possible?

The Classic Lancer Kotl comes to mind, especially with the CD reduction on Chakra now.

My friend and I adopt DK Kotl because the combo is really strong too, makes for a strong harass lane.

For a kill lane, a -armor one is pretty tough early game, like VS + Tide (yes, you can play him in a dual lane).

And Axe + Dark Seer, the nightmare cuts are here, while he has Ion shell at max speed.

Also, my friend once went Leshrac, Ursa, and Oracle in a trilane, the kills just kept coming. Fun times.

my friends and I ran an offensive viper bounty veno tri-lane for yolo, 20 kill lead later, man that was aids

Axe+ Tiny <333
With this combo Axe is not useless without dagger. Amazing kill potential and burst damage.

Outworld devourer+ Skywrath Mage is scary too. I mean- infinite harass.

Dark Seer and Spirit Breaker is a little obnoxious.

As are Rigrawl dual lanes with like and Undying or Witch Doctor to keep him alive.

Oh and Axe and Dazzle. That lane is disgusting.

Roaming SD + Dazzle for ez kills on all lanes.

I'm surprise no one said necro yet. I think if you mean the most annoying lane to go against it's probably necro + skywrath/dazzle/witch doctor

Mr. Bane and Mirana/ Visage and Drow Ranger/ Axe and Omniknight dat Berserk Call and Purification dafuQ.

Skywrath himself is the nightmare of all offlaners, long range harras and you can't harras him back.
Huskar with veno would be pretty insane. Huskar could get off so many stacks of fire arrows with the help of veno. Every time gale is off cd and the enemy isn't at tower=free kill.

I played today vs the Axe+ Omniknight thing... ;_;
