[Zircon]

I'm new to Omaha and need some advice on which hands to raise, because my PF Raise value is too low (3.3 %).

Say I am on the button in a loose-passive game, and there are two limpers. Of course I would raise double suited aces or JT98 ds, but how about these hands:

a) QcQhJh9s
b) TT88 ds
c) KsKd7d6c
d) JcTs9h8s
e) 8877ds
f) QJT7ds
g) 8764ds

Some general guidelines?
Thx.
