Hi, this is my first post about roulette system, hope you can give feedback about progression or any other thing that help this system. We need 8 unit to play this one, first we put one unit on street 1,2,3 and one unit on split 10,11 the other 3 units is on 2nd dozen and other 3 units on 3rd dozen. So far I've been playing flat bet and almost never loss, but with better prpgression, I think this system will run more perfect.. Sorry if my English is bad.. Thank you for your attention..
