55 in $220 HU debate

[ig06]

Just playing around with pokerstove, you range from 55-45 favourite if he is pushing top 70% of hands to 55-45 dog if he is pushing top 20%. Even if his range here is ATC you are still only a 60-40 favourite (and I wouldn't imagine ATC is credible), so if he is really that bad (and given its a SNG rather than cash) maybe you can find a bigger edge before the blinds get too big?
