Fundamental? Technical? Something in between perhaps? I basically use the technical approach primarily using systems. The systems I use are all based on a minimum of 2 years testing for consistency and obviously good results. I won't use any system that doesnt AVERAGE at least 60% over the most recent 2 seasons. It doesn't guarantee a thing but I believe you're eliminating emotion and subjectivity as much as possible and staying with "proven" historical data.
