***NEED HELP TESTING***
This may be one of my best performing systems, played with 1 DS and a simple negative progression, "Six Savior" had a 90% winrate, 45/50 Games won. Only difference with this one is the betselection; The dozen before the current one hit is bet (At the unhit DS of that particular dozen);
For an example Doz 1, Doz 2 has hit; Now you bet doz 1 (the dozen hit before the current hit); and let's say DS 1/6 was hit within doz 1. Therefore you bet DS 7/12.
Bank/stoploss; 500u (played with 1u bets).
Progression: Do 6 spins, Then double bets. After that double bets after each 3 losses in a row, until hit.
