The first round of the RBC Heritage gets underway today and with that, we have an unprecedented part 3 of our most interesting pictures from the event. As a refresher, the field of 134 is battleing on the tight treeline Pete Dye designed course, for the $7.1 million purse with $1.28 million going to the winner.

In part one of this week’s “most interesting photos”, we covered putters, for part two we covered some of the action around the course, and for part 3 we have a little bit of both.

Don’t forget you can check out all our image galleries in the GolfWRX Tour Equipment forum.

Snedeker with that “new driver” look

The 2012 FedEx Cup champ is quietly one of the biggest driver testers on tour, and he was looking thirsty at a couple of TaylorMade SIM2 drivers on the range. Also noted his Miura CB-301 irons.

Build your own training aid

Path board – check, digital level – check, alignment rod – check, extra club – check. Why spend all kinds of money when you can just build your own simple training aid?

Its armlock – but backward

Matt Kuchar brought the arm-lock style to the PGA Tour and it looks like he might be changing course again since he was spotted testing a “reverse” arm-lock Bettinardi on the practice green of Harbour Town links. This is a reverse style because the grip rests against the trailing arm versus the lead one.

Maybe graphite is the new steel

We’re not sure whose caddie this is, but the interesting thing in this photo is the graphite shaft in the putter. Although Bryson wasn’t the first, he certainly has opened the door for more players testing and putting ultra-stiff graphite shafts into their putters for stability.

Si Woo, and Charles Howell talking putters

Everyone knows Charles Howell loves to talk gear, and here he is chatting with Si Woo Kim about a couple of putters—just imagine the nerd level conversation being had.

Na continues to test the new Callaway Epic

Kevin Na is one of the last holdouts on tour with an original Epic driver in the bag, and again this week we spotted him testing one of the new Epic Speed drivers. Considering his chances this week based on the course length, it will be interesting to see if he officially made the switch.

 Maverick’s unique Toulon

Maverick McNealy’s slant-neck San Diego has a very different shape from the retail version and looks to be both longer heel to toe and also shallower—it reminds this writer of the classic Ping Anser 4.

Davis Love III has a full bag of familiar sticks

Davis Love has won the RBC Heritage 5 times (yes, 5) and this past champion has a full bag of Titleist gear including 718 AP2s and SM8 Vokey wedges. You can get all his full WITB here: Davis Love III WITB RBC Heritage

Who has 2 thumbs and loves to test putter? Matt Wallace

Matt Wallace was working with a number of Toulon putters Tuesday, and although they all had something a little different to offer, the one thing that stayed the same is his preferred 2-Thumb grip.

The grind doesn’t stop for Furyk

Did you know Jim Furyk is 3rd all-time on the PGA Tour career money list with over 71 million buckeroos banked. Crazy right? So imagine the drive it takes to continue to work your butt off week in and week out on both the PGA Tour and Champions Tour to find every edge.

Speaking of edge, Jim was seen on the range working with Callaway tour reps on a Callaway Epic Speed triple diamond to hopefully gain a few mph of ball speed. Gotta respect the grind.
