you can play TAG or LAG at low limits and win either way, but winning by playing LAG takes much more effort. plus if you like to multi-table it is much harder to play LAG when you play a bunch of tables especially when just starting. players are pretty bad at low limits so LAG might get kind of tiresome if you're not really good at it. as far as what hands to start loosening up with...suited connectors are probably the 1st group of hands to add - don't just start playing any 2 suited cuz it gets expensive.
