Fair question. I've been messing around a bit and I really like the final formula that I have for both sets. They are finalized as is. Word to the wise on the all-madden set, you will struggle against good teams. I'm currently getting trounced 28-10 at the half by the Falcons,but that includes a pick six. Game should be 21-13. I lost to the Saints 35-30 in week 1. I'm gonna finish the Falcons game tomorrow, and then I'll be interested to see how I fair against Tennessee and Baltimore respectively in weeks 3 and 4. I'll keep you posted.
I definitely like the 50 parity with the all-madden set. You have to play smart , and play several games. You'll see a variety of results. Minimum all-madden cheese, which is great.
