? about scoring categories in Roto leagues

[AuburnTigers]

I have always played roto using the standard 5x5 stat catagories. After seeing several leagues that used OBP instead of BA, I felt that was a much more logical stat to use since it gave walks value. Also my main ? has to do with replacing HR with total bases. Could anyone give me their opions on making the switch from HR to TB? Or would it be better to add TB as a 6th scoring catergory? Any info or opinions would be greatly appreciated

If I was using OBP and was going to replace HR I'd probably go with SLG instead of TB.
