I dont understand...
"The reason I want to devote my time and energy into this thing is that I have found a game that gives the player a far less disadvantage than the traditional blackjack game, provided you are able to play perfect basic strategy-which is no small feat. "
Actually, according to Wongs CBJN (April), the basic strategy SP21 player has an off the top disadvantage of .82%, which compares unfavorably to a disadvantage of .41 to .63 for your typical Strip 6D shoe, and even less favorably to the decent double deck of .25 to .35 that is readily available in Vegas (of course depending on the sweat level). In fact, to use a comparable game, "Super Fun 21" which we all know is a rip off (although not as bad as 6:5) is a .94% disadvantage, only .12 worse then SP21.
Bottom line, you are at a huge disadvantage with SP21 off the top and although you could beat the game, you would need abnormally large bet spreads as Sentry suggested. You are better off just putting SP21 into the same catagory as SF21 and 6:5. As for why there is no sim package for it is quite logical to me...those of us who are serious enough about the game to invest in a sim package wouldnt think of SP21 as anything but cover and comps, thus a typical basic strategy guide would be good enough:)
At any rate, best of luck.
