This is a great progression/method that can be used playing with any 2 doublestreet strategy:
It's a negative progression, +1 bet each second spin without a hit. Reset at 2 hits in a row. OR when bankroll is positive,
Progression will look like this
1 1 2 2 3 3 4 4 5 5......and so on. +1 each for each two losses in a row. (No progress when hit.) ...Start to calculate for 2 more losses and +1 bet after 1 win. Until 2 hits in a row, then reset/restart. Sometimes afew more hits is required to get a new high when the progression has advanced a bit,...
Try it out, for me it works just perfect.
It's a very mild progression that can survive many losses AND recover quick when it starts to hit.
isn't that Penthouse?
