In 2012, Wilson reintroduced the Prostaff line with their Amplifeel series of rackets. Among the new rackets were 3 "Pro Staff" branded models: a 90, 95, and 100 square inch headsize. There has been a noticeable difference in swing-weight in these rackets, with the 90 having a 327 swing-weight, the 95 having a 306 swing-weight, and the 100 having a 304 swing-weight. The more modern Pro Staffs have also a reduction in weight; the 95 and 100 boast 11.5 and 11.3 oz strung weight, respectively. In comparison, the original Pro Staffs were very heavy, at 12+ oz.
