When I first started trading options, I was only doing spreads. Here is where I ran into issues:
1) When your spread goes ITM, it's going to cost to roll. Last summer, I had a number of spreads go ITM, and it took 3-4 months of rolling the entire spread before they were OTM. Each roll was a debit. Subsequently, to manage the margin, you could only open spreads for a portion of your available margin in order to handle situations where you go OTM.
2) With spreads, you can make your short strike further away from ATM, but to generate significant income, you have to open a large enough pool of spreads such that if you wanted to close some of the long legs, you don't have enough margin such that you can close all of them without also closing the short legs. So the spread legs are paired together. For example, right now I have 24 naked puts on RUT at $650 strike that generated around $22K of income when they were opened. To generate the same income with $620/$610 bull put spreads, I would have had to open nearly 200 spreads. With that much leverage, it gets harder to roll or adjust when the market has moved aggressively toward my strike. However, with 24 naked puts, when the market does get closer to my strike, it's a two legged roll that generates income to go further out and down. I make sure that I never open too many put contracts such that I couldn't continue to roll out and down.
