Can't say what would happen at Soaring Eagle as I haven't tried it there, but IMHO in Vegas 6:5 single deck games, the pit often believes it to be unbeatable. So they often hardly give it a second look.
If you hit and run, you can pull off some outrageous stuff with impunity, LOL.
I've counted down SD games there (even back counting) to the occasional MONSTER SD count (think +18, even +20 LOL) such that the remaining 2/3rds of the deck are nearly 60% all 10 & Aces.
Tossing out a stack of black when that moment arrives (even after noodling around on the game with just REDS for over an hour) in such circumstances often gets a knowing grin from the dealer (if she's friendly) but never the kind of heat that you'd get trying a stunt like that on a normal game, LOL.
Of course it's still always a good idea to take a break AFTER something like that goes down (even if you lose the hand, or more likely push twenties!)
And you have to wait a LONG time before you get those opportunities (it tries your patience being bled slowly on such an otherwise crappy game, but hopefully it's just nickels or even DOLLAR units being sacrificed) BUT when it does happen, and you get that sweet NATURAL that you KNEW was coming, it's a nice hit even at the reduced 6/5 payoff on the stack 'o black, LOL.
Overall, 6:5 still sucks monkey balls however. Best situation is still to apply the above on a good ol' fashioned REAL 3:2 SD game.
Gawd, I love the Sweaty Spaniard, LOL...
Been away too long: maybe time to book a trip downtown LV, heh.
P.S. I did get backed off at 4 Queens once, doing basically this... not "spreading" exactly 1-16 but more like Hit&Running spread 1 nickel unit to plunger 80 units ($400) on those monster counts when I just KNEW the dealer was standing there holding a handful of all paint cards. That time, it was last day of my trip and I was playing unrated and didn't really care if I was tapped 'cuz I knew I was not gonna be back in town for at least several months. The pit critter who tapped me and escorted me to the cage was actually kind of laughing as he showed me the door... heh
P.P.S. Heh, just for reference now I checked it by editing the deck in CV to a +18 condition. Player edge 9.20%...
