OP, the problem with options is that there is no absolute 'best' , any option play or structure is good under certain circumstances, bad in others. A screener works according to your search criteria, but you must know what you are looking for. In general selling naked like you do is not recommend, but if you really want to do it you must make sure that the premium you receive is rich enough to compensate you for the risk you take. For knowing this you need to research a bit implied volatility, and try to do your selling when IV is high enough and you expect it to drop. And sell few contracts close to Atm rather than a bunch of otm wings, that is the recipe for disaster.
