You could certainly be profitable with a looser style but I feel at 25NL when you're just getting your feet wet a tighter style is much more effective. The main reason is when bluffing is not profitable because of a steady stream of stations you're relying on hand value a LOT. Playing tight means you'll be coming into pots with much stronger hands on average which is pure $$$ for you.
Flyingpenguin you play BW? I see someone with that ID on west realm quite a bit.
