Here's Vokey Tour Representative Aaron Dill, hard at work in Waialae's bag storage room/makeshift workshop.

Here Kelly talks with Titleist Brand Ambassador Marc Leishman, who shot a 60 during one of his warm-up round last week at home in Australia. Marc's Scotty Cameron Circa 62 is working just fine.

Here's a look into Leishman's Titleist bag: Marc plays a mixed set of Titleist irons (AP2 2-4, MB 5-9) and carries three Vokey wedges (48, 54, 58), featuring a little rust from Australian ocean breezes.

Titleist Brand Ambassador Joe Affrunti is making his first start this week as a PGA Tour rookie. Affrunti earned his card by finishing 22nd on last year's Nationwide Tour money list.

Let's take a look inside Joe's Titleist bag...

Joe also carries Titleist AP2 irons with True Temper Dynamic Gold shafts...

And four Titleist Vokey Design wedges: 48-06 (bent to 46), 52-08 (bent to 51), 56-10 and 60T (bent to 61).

Here's a close-up of Joe's Scotty Cameron Newport Squareback Select prototype putter.
