Oh and I looked at some pokerstove results just putting hands in our range up against a random/100% distribution & even with a hand like
55 we have 60% equity
KTo " 59%
A8o " 59%
A4s " 59%
QTs " 59%

So I guess I'd definitely be 4betting this range and getting it all in pretty light (calling a shove, c-betting (& after 4bet pre) being pretty pot commited on most boards.)

Personally I would probably shy away from playing too many hands below this 60% threshold because it seems like its going to be fairly easy to get your money in fairly frequently with a big edge.

(I think you're probably referring to a hyper lag or something at higher stakes in this example but it happens quite frequently vs drunk guys at low stakes and you can really sit back and pick your spots vs them as opposed to trying to play hands that are like 53/47 vs their range.)
