BlackJack SideBets Bonanza

I was at an casino recently playing BJ that had what I think are some very beatable side bets. I would like to know mathematically if/when to make the side bets based on the True Count.

Table rules were:

6-Deck Shoe
Dealer Hits Soft 17
No Surrender
Split any 2 cards, Up to 4 hands (Split Aces once)
Double Down on any 2 cards

Here are the side bet offers based on your 2-card total and the payoffs:

2-card total of 17-20 pays 2-1
2-card total of 17-18 pays 6-1
2-card total of 18-19 pays 6-1
2-card total of 20-21 pays 5-1
2-card total of 17 pays 12-1
2-card total of 18 pays 14-1
2-card total of 19 pays 15-1
2-card total of 20 pays 8-1
2-card total of 21 pays 19-1
PAIR pays 12-1

Obviously the higher the True Count the better odds you have of being dealt a high 2-card total. When the count would get positive I was placing a small side bet on getting a 2-card total of 20 and/or a Blackjack, which pays 19-1. I happened to be dealt 4 blackjacks in a row while doing that which added to my bankroll nicely.

My question is, what would the True Count need to be for each of those sidebets to be profitable betting long term?

Thank you.
