Combined advantage and progressions isn't so simple....
I tried to do this a while ago...
Basically, positive counts won't last long enough for the progression to have a decent effect.
If you use a neg prog. with the count, you might have a losing streak on a high count, and then find yourself high up your betting ramp with the advantage turned against you.
Using a pos prog. seems more sensible. You only up on wins, which will occur slightly more frequently on pos counts, but you may also get that DD, SP or BJ on a large bet. It's also easy to bring the bet size back down when advantage is turning, or has gone.
It'd lead you to to quite a bit of wonging, and I don't think it'd be as profitable as counting (more efficient).
Also, you will be overbetting using a progression.
It just seems easier to count, instead of tying in a progression to advantage play.
