laying bad teams when at home

[rob in america]

  I always like the idea of either laying bad teams or backing their opponent. But too often when the bad team is on the road the odds reflect that and potential winnings are thus pretty low.  I'm looking into the idea of focusing on bad teams when they are at home. Today we have the Swiss Challenge league bottom dweller Aarau, who have one draw and six losses on the season hosting Schaffhausen, a mid level club who haven't been very good on the road, but I still like their chances at around even money/draw no bet. My idea is to look for these bad teams when playing teams a notch or two higher in the standings when a draw no bet option is anywhere from around 1.8 or above on the road team.  Anyone looked into something like this?
