I have a two person dynasty going and we have entered our 7th year. We play on all american and we both have only lost 3 games each in those 7 years.
It was getting boring so I went online and found some sliders people have made. We tried about 4 different sets and none of them where what we were looking for. We then tried this set and for the most part we have been having very close games, we also have lost 3 games each this season using these. The only thing we didn't use on this list was the special teams and we kept that at default, we also kept the game time at 5 min. each. and user qb we adjusted from 0 to 40
Here is the list if anyone else can't find the balance there looking for.
