I generally middle the following numbers when getting 1 point:
NFL 3, 7, 10, 14. 3 you can go well past -110. 7 a bit past.
Totals 37 and 41.
CFB 1, 3, 7, 10, 17, 24, 28, 31. You can go a bit past -110 on 3 and 7.
There are other numbers that work out when getting reduced juice, but I generally find the profit to time involved on other numbers is kind of pointless.
4 and 21 warrant a glance from me if reduced juice.
If getting 1.5 + points, you are prob ok on any side number and 2 points ok on any total.
