It depends on the faced up card of the dealer if you will double down on soft 17 or not. Remember that Slaman didn't mention the faced up card of the dealer and you just assumed it was small. I'm assuming that dealer faced up card was 7 to 9 when I made the comment above since Slaman still hit at soft 17. Slaman provides only the data that the dealer total card was 11 and when the dealer hits 6 to make 17 which means there's a chance that dealer faced up card is around 7,8,9 too and not only 6 below that's why I'm checking this info to him on my above post.
I would assume that everyone has a different strategy based on each situation as well. Each scenario is a different one and each person plays differently as well which means that strategies will be different on what to do based on the person and the situation. This creates countless number of possibilities on what to do next on every single hand, and you will see people derive from the usual a lot based on what they like.
I personally do not even look at the dealers cards all that much, because I feel like 17 or lower is a bust for me anyway, doesn't matter if they have 5 or 2 or whatever, so if it means I have 16, I hit, and not everyone is like that for example.
