HU, how big a stack differential becomes significant?

[Lottery Larry]

In your opinion, in heads-up play (whether cash or tourney structure), how much of a stack difference is required to make things one-sided?

Let's assume the ratio to the blinds is very large, so that's not a factor (think 60:1 or greater)

Is 55:45 too much of a stack edge? 53:47? less?

In other words, if you were the shorter stack, how much of a difference against less than world-class players would feel like an "unfair" disadvantage?

BTW- $6000 vs $5300 is close to 53:47

Thanks
