Several years back (2009?), as I dipped into the plus-handicap range that season. Played the same PROV1X for 7 consecutive rounds. The highest round I carded during that 7-round period was 75... almost lost it on the 7th round, but found my ball, as I was sure that it had finally met its' watery grave, only to realize that it had nestled into some deep rough just short of the creek that protected the green.
Finished the round with it. Scuffed, beaten all to hell, with it looking like it'd been put in a mulching machine - I finally decided to retire it and throw it into my shag-bag for practice.
7 rounds with the same ball.... looking back on it, especially considering how much my game has deteriorated in the years since - I should've put that ball in a frame like I did with my three holes-in-one balls, as it was probably just as great a personal accomplishment.
(waiting for Typhoon to post that he played half a season with the same ball, which given his level of talent - wouldn't surprise me).....
