Out of curiosity, why 1H?
I know in the past you have said 17, 20, 24 are key 1H totals and I know you often play the 1H total when the game total is not on a key number (47.5/24 for example)
In this case, with the choices 43 or 21, I would think the better bet is to take the full game and extra point, but I'm sure you have your reasons (Maybe these two play slow opening halves or something)
Anyways, just wondering...
Good luck - and no reason to say I think after one bad day - you know your bets are solid and no less solid today than a month ago
