Since the death of “wound" balls when it was important to 'wrap' the windings in a consistent manner and sort them to their compression. The advances in solid core, two, three and four layer balls allows manufacturers to build in compression and to use “flobber-like” cores and thin mantles and covers to propel balls with whatever characteristics they need. Jack never had a ball designed for his game, nor did Trevino, or Watson. Today Tiger, Els and others have their own ball.
The ProVI has a compression of as ladies ball of ten years ago.
