This is an experiment so far, can't say anything for sure yet, (more testing is needed)...
Procedure: For each DS hit, bet the 3 numbers of the opposite color within that particular DS. do this until 3 Doublestreets are bet (3+3+3 numbers) When 9 number bet, place 3u on the remaining 3 DS. IF any repeats (or Zero hit) before 9 numbers bet (double once), then spin, OR else spin, and then double for each loss, until hit, (or until stoploss is reached).
wingoal: +200u
stoploss: -200u
BR: 300u
