dagnyt,
You should realize that even if the number of contracts is the same, the risk is higher on the FOTM spread. Taking in less credit per spread results in higher margin requirements. By doing the same number of contracts you've effectively taken a position that risks more and gains less than a CTM position with the same size.
Really though, size is irrelevant. A losing strategy loses regardless of size, and a winning one also does so regardless. Reducing the size doesn't increase your chances of winning in the long run. It only serves two purposes.
1) Reduces your profit potential.
2) Prevents a blowup.
If you've found that you can make money consistently for 10 years with your strategy then it is a winning strategy. If you faced significant drawdowns during 3 sigma events, then it is a losing strategy and needs to be adjusted. I also do a further OTM credit spread on occasion, but not as a standalone position.
I would suggest to anyone who might be uncertain about the ability to manage a CTM spread. It is much easier than managing an FOTM spread that has gone wrong.
