Sorry if the title was catchy but i think it all boils down to this when you a real pro.You dont leave because the wheel is going bad,what ever that is,because when the wheel is going bad for someone,i bet it fits well into another startegy.So in general we all wish for the day when we call it a day from roulette because ,gosh we are tired of winning,time for a rest and be back another day :xd:
