I am curious as to how much you are betting on these. If that is only a small amount which is just intended for fun then I guess it is all right. But if you are betting with an amount big enough to make you scratch your head all throughout the day then I think you should reduce your parlay bets to around 3-4 games.
I believe he is asking for the opinion about his pick and not an advice about the winning probability of the parlay quantity pick match.
I notice you pick the team with high probability rate which is usual on parlay. Picking the other side will be more riskier so your pick is right.
