I have a friend in US. He claims to play American wheel by visual ballistic and being able to cover sectors of consequtive numbers with outside bets plus some little inside action.
If one will look closely to American layout, dousens have high sector coverability. Unfortunately, edge to sustain such a play should be kind of high, but it's sertainly possible. If one will find single drop point wheel, could place predictive bets on outside and yet look like system player.
For example, this thing of betting dousens with little progression gains new meaning if we know wich of them is more likely to hit ( due to prediction by vb).
I myself do not have American wheel layout memorised yet, if l happen to play such a wheel , l will consider this possibility high.
