DAS
Your point about DAS vs non-DAS strategy is well-taken. I do agree that if someone is going to play a mix of DAS and non-DAS games, then he/she should learn the differences in splitting strategy.
I encouraged the poster to learn the multi-deck S17-DAS partly because of his geographic location, which I inferred from his E-mail address. In his area, the almost all of the games are multi-deck S17-DAS. So this would be the correct BS for almost any game near him.
In fact, most Shoe games are DAS. Right now, I cannot think of any that are not. There are some double deck games that are not, and some that are. But with more than 2 decks, DAS has become kind of standard.
Of course, most single deck games are not DAS. They are also often H17. If someone wanted to play primarily handheld games, then I would encourage them to learn a non-DAS strategy, probably with H17.
