two team parlays

this seems like the best bang for your buck i only bet football but what i useally do is is pick the over under with the team i like then ill lets say i put 300 on said team then ill go 200 on the total and the parlay 150 . would love some imput what do you guys do what style gives you best odds

if you can hit 58 pct. of you games then you should play parlays, otherwise stick to straight bets. at 58 pct. your roi is better than straight bets.
