Hi, before I get started I want to say that heat is not much of a factor at my target casino and making the most (getting as much ev for a little risk) is my priority.
Recently I hit a few bad runs that really put a dent in my bankroll, so I'm looking for alternative games to reduce my risk.

The comparison is between a DD and 6D
both have the rules of H17, DAS, OBO, NS, no limit on amount of replits except aces (standard rule of no hit on split As)

the DD has 50% pen, double only on 9, 10, 11. You can spread fairly large, but I won't be able to b/c of bankroll considerations
the 6D has 83% pen, double on any. You can reasonably spread 1-16 on just one hand.

I'll wong in and out of the DD. Again, heat isn't really an issue here. I've walked to the table w/ only a few min bets, and gave off the appearance of a gambler waiting for the right moment for a comeback. Plus the casino is pretty low heat in general.

The 6D, I'll wong out but won't wong in.

Should I stick to the 6D or move to the DD?

I'll answer any questions to explain the situation better.

Thanks in advance!
