Hits and OPS or OBP and TB

[walkoffblast]

7x7 league. In the past we have played Hits and obp plus the normal 5. I realize hits is kind of redundant when avg is in play but it adds a nice balance of player value between top of the lineup guys and power guys. Ideally I think I would prefer to get rid of avg but that would be a tough sell in my league. So which do you think is best and why? Also, any other category I am overlooking?
