Scotty Cameron Studio Design 2.5. First introduced in 2002, the Scotty Cameron Studio Design 2.5 is a rounded flanged blade with a pocket. This affords a clean look at the ball, and made for the player demanding precise feel and feedback. In addition, the 2.5 features a rolled topline and a high toe for a distinctive profile. The exceptional features that set the Studio Design models apart - milled from soft carbon steel, flowing necks and a re-designed grip are all part of the Model 2.5. Scotty is always looking to refine his putters and in 2003 the 2.5 received a new finish called Black Pearl that is nearly maintenance free. This finish, with its dark smoke color and iridescent look, has great sound and feel as well as being rust resistant. Scotty Cameron putters are generally considered the best in the world and used by numerous Titleist staff Professionals including Ernie Els and David Love III.
