Can Single Deck 5 to 6 be beat

I know the conventional wisdom is we're supposed to avoid the 5 to 6 single deck bj game like the plague since it starts with about a 1.4% house edge, which is hard to overcome. This is probably why this game isn't discussed much in main stream bj books.  I've spent some time on the internet researching this game and I find conflicting advice on various bj forums on how big of a bet spread is required to beat it, and when the player actually has the advantage. Is it at a +2 or +3 count?

I bought CVCX last month to analysis a single deck 5 to 6 game I accidently came across  in a casino about 5 hours from my house.  This game deals all the way to the last card. The only card not seen is the burn card.  Most of the time shuffling occurs in the middle of  playing a hand.  With the exception of the 5 to 6 rule, this game has very favorable rules, with S17, double on any two cards, das, and rsa.  With a 1 to 4 bet spread, CVCX gives it a SCORE of around 100, and a 1 to 15 bet spread gives it a SCORE of appr. 300.  Since I'm calculating such a high SCORE for this game, I feel I must be doing something wrong.  I'm still learning how to use CVCX.

My broader question is can the single deck 5 to 6 game be beat?  Since penetration is so important, does a 100% penetration overcome the 5 to 6 rule?   Is it worth side counting aces (which is easy to do in single deck) in this game?  At what count does the player start having an advantage in a 5 to 6 game?

I have won playing this game but I know I haven't played it long enough to get in the long run so I might be fooling myself into thinking it can be beaten.  I've varied my bet spread from 1 to 15 without any heat.  The casino pretty much ignores this game compared to how they watch the DD game.  Any help or advice is much appreciated.  Thank you!

Short answer: NO. 
You'll need to be at True +4 to break even,  True 5 to be somewhat over the top, and that doesn't happen as often as you'd like.  Your bet spread will barely keep your head above water,  or more accurately, barely within snorkel distance of the surface. You'll need to use all your indexes,  and apply the Ace where you can.  But remember, most of these indexes are to minimize your losses.  A Level 2 system would help. I think I know the casino you describe,  but with any 6:5 ride, the roller coaster always stops at the bottom.

The incompetent  floor will sweat and backoff 6/5 games as well

Thanks for your comments.  You're probably right.  This is why I don't play this game much, but it does intrigue me, especially since it's dealt all the way down to the last card. 

The following article says that a 1 to 8 bet spread can beat this game.

CVCX shows that a player has the advantage at a +2 count, which this article also says is when the player has the advantage.

I also recently bought "The Big Book of Blackjack" by Arnold Snyder since I read on a bj forum that he had a section in this book where he discusses "Experto Blackjack", which is similar to the game I found, expect it pays 1 to 1 on blackjack.  Experto Blackjack is no longer around but it was also dealt down to the last card and Snyder said expert card counters beat it.

I'm probably not in the category of an expert card counter so I should stay away from this game.  But I still play it occasionally.  The other thing I like about it is the table minimum is $5 and I can easily spread to two hands of $70 on each hand.  I could never get away with this on Double Deck, not to mention there are no $5 DD games.

BTW, I really enjoyed The Big Book of Blackjack.  I've got over 20 bj books but I had never heard of this one.  I highly recommend it...it's entertaining, gives a great history of blackjack and he gives some great pointers on how to survive as a card counter in a casino.
