I've been toying with an idea and not sure the best way to go about it. Hopefully you guys can help me refine it?
The idea is do a flat bet and a progression at the same time.
5 10 20
5 10 20
5 10 20
The above is a small chart, but larger one can be made.
So bet a full column, 3 spins for 5 units each spin. If you win 2 out of three, then you won the column and can reset. Betting down the column is where the flat bet comes in. If you lose on a column, then move to the next column.
Here is where things get tricky. As you play down the column, you are also playing a progression on a row. So you can move the row bet from the second column to the first column on a win. You can also keep track of your wins going down the column and reset the column on a win.
It gets even more elaborate, you can take the win and instead of resetting the current row, take a couple wins on the column and instead reset a row with a high progression bet.
