Screw dem bastuds (Score 1)

A carefully constructed salary history is your best friend. Just keep it consistent. Your salary requirement should be ~25% of your current salary; therefore, your salary history should be such that you appear to be asking for a modest (9-12%) increase. Unless, of course, you have less than 2 years experience. Then you can easily double your leverage.
