addyor, what I mean in regard to parlays is that they cause huge variance so your results won't ever be consistent. You can't achieve consistent monthly success in sportsbetting anyway unless you just scalp. Just no way to make enough bets.
The other thing about parlays is that it forces you to bet at the same book, instead of making each bet separately. This will affect your ability to make each bet at the best odds available which will lower ev and increase variance even more.
As for you picks, good luck.
