Tight table, online casinos and day of the week.

At times, the only table is one that has 30-50% seeing the flop. How do I go in and break open the table? I adjust my play via Agg/Pass and L vs T, yet I can't get any momentum going. Other than jumping sites, how should one approach this to be more successful?

If I can't get any actionable cards, I will change tables. After 3 or 4 tables, I will change sites. Anyone do this or have any thoughts regarding it?

Minus the peak hours/days (Fri+Sat), what are some of the good ideas/conciderations to have when approaching the rest of the week/days? Thx.
