-0.26 for one deck (ha!), -0.21 for double deck, and -0.18 for a shoe game. This is less than the difference between a double-deck game and a 6- or 8-deck game, so all other things being equal, a double deck double on 10 or 11 game is better than a shoe/double on any two cards game.
I remember when I was first learning to count and trying to memorize the soft double index numbers, and reflecting that soft doubling risks your having to stop dead when if you hadn't doubled, you would have taken another card no matter what, like if you double on a soft 13 (A-2) and get a 3. So soft doubling does reduce your win percentage (but the doubled bet makes up for that, of course).
But the basic strategy player isn't losing out that dramatically by not being allowed to soft double. A good rule, like dealer stands on soft 17, can negate that disadvantage. Stuff like double after splits can make up for it, too. That's why it's a good idea to memorize all the pluses and minuses of BJ rule variations. The LVA article I linked to spells it all out.
It would take more like 4 hours to get to the wine country from Reno, but it's a gorgeous drive.
I did that drive in early March in 1987 from Geyserville to Reno in just under 4 hours in in a rag top Ford Mustang. We stopped in Truckee for goodies and drinks. The carton of milk was frozen by the time we got to Reno. Beautiful country, that's for sure.
The only time I was ever escorted off a casino floor was at Circus Circus Reno on this trip. Turned 21 a month later. But what pissed me off was a girl running around from machine to machine yelling like a banshee, wearing a letterman jacket with 1987 on it. What the hell?
Had some nice trips to Reno. Saw Ray Charles in one of his last performances there on my first wedding anniversary. Good times.
