What's your biggest comeback Heads Up?

[mblax10]

Last night, I went to heads up of a 1 table NL S & G outchipped 10,773 to 2,727 with blinds at 200/400 + 25 ante. I fold my big blind the first hand heads up and go on to win the next 7 hands and the tournament.

This reminded me of my biggest S & G comeback. A couple months ago I got heads up in a 2 table S & G outchiped 25,580 to 1,420. With blinds at 300/600 + 50 ante. I double through a few times and end up winning a good heads up battle.

I'd like to hear some others' biggest comeback heads up.
