In Vegas if you shop around you can find some nice spots to take shots, especially on ones where they actually pay better than average odds.
So you can usually get 3-5 games a week where you can have middle shots, ot outright no lose shots, especaily early in the year, and especailly in NCAA stuff.
Similar to the contest cards, nmost cvomeout Tues night or Wed morn so you have 4-5 days worth of lines moves to work with. So you can ayke the teams on the card, then use those teams off the board as well to get free shots at some not so bad pay off.
Those are the few times I say betting parlays is worth it. But you can usually get 7/5 guaranteed and sometines upwards of 2/1 if you get the "right number" at the "right odds".
