I don't want to come across as preachy or condescending, but teasing college games (and point totals) is generally not a good play. There is too much volatility in a college game and it's not worth the price you are paying to move the line. Generally, the best EV teasers are Wong teasers, which is teasing NFL +1.5 to +2.5 dogs up and NFL -7.5 to -8.5 favorites down (through the key numbers of 3, 6, and 7). I believe they were originally supposed to be home teams (at least the dogs), but with decreasing HFA, that is not a hard rule anymore. I wouldn't tease anything else.
PS. Parlays typically are not good plays either unless they are correlated (ex. Dog + Under pt total in low scoring games). And never ever parlay 2 teams playing at different times. You will make more money betting Team A and then betting your winnings on Team B. There is a reason parlays are big money makers for books.
