The Titleist Tour Support Vehicle was parked this week at Killarney Golf & Fishing Club, where the European Tour has returned to play the Irish Open after a 20-year absence. Players teed off this morning on the picturesque Killeen Course, set on the banks of the stunning Lough Leane. We've got some especially impressive views from the back of the TTSV (as you will see in the slideshow below).

Here are some Titleist player equipment updates from the week, including more activity involving the prototype Titleist 910 driver:

• Titleist Brand Ambassador Matteo Manassero (pictured above), 17, had been looking forward to testing out the 910 driver this week in Ireland, his first opportunity to spend some time with the Titleist European Tour Team. (The Titleist 910s first hit the European Tour four weeks ago at the Barclays Scottish Open.)

The result? A massive smile on the young Italian's face – not to mention increased ball speed, higher launch and great spin numbers. That all added up to an extra 15 yards in the air, and increased total distance.

Manassero, who earlier this year became the youngest player to ever make the cut at the Masters (36th), also found that he was able to turn the ball over with the 910 better and without losing some control, which he found especially significant.

Matteo's Titleist prototype 910 specs:
• 910D2 9.5
• Project X 6B7 (tipped 1.5"), 45"
• Tour Velvet 58 Round (1+1 reversed)

He put the 910 straight in the bag.

• Unlike Manassero, Titleist Brand Ambassador George Coetzee was turning the ball over to the left a bit too much for his liking. After a few twists and a click on the adjustable 910, Goetzee, one of the biggest hitters on the European Tour, was going at his ball hard without the fear of losing it left.

Coetzee's Titleist prototype 910 specs:
• 910D2 9.5
• Grafalloy ProLite 3.5 X ( tipped 1.5"), 45"
• Tour Velvet Midsize

Coetzee also ordered a new set of Titleist CB irons, having worn out his latest set from hours and hours of practice.

• Also switching to the prototype 910 driver this week was Titleist Brand Ambassador Peter O'Malley, one of the straightest drivers on the European Tour (he is currently ranked second, hitting 75.8 percent of fairways). O'Malley put in some work on the range with the TrackMan launch monitor, eventually choosing to go with the 910D2 10.5, because it gave him an extra little bit of spin and helped keep the ball in the air a little longer, as opposed to the 910D2 9.5.

OMalley's Titleist prototype 910 specs:
• 910D2 10.5
• Aldila Voodoo XVS6 ( no tipping), 46"
• GripMaster Round 0+1

• The list of European Tour staffers now gaming the Titleist 910 drivers is as follows: Andrew Dodt (D2, 8.5), Brett Rumford (D3, 10.5), George Coetzee (D2, 9.5), Jose Filipe Lima (D2, 9.5), Kenneth Ferrie (D2, 10.5), Mark Haastrup (D2, 7.5), Martin Erlandsson (D3, 9.5), Matteo Manassero (D2, 9.5), Mikko Ilonen (D2, 8.5), Pablo Larrazabal (D2, 9.5), Peter O'Malley (D2, 10.5), Ross Fisher (D3, 7.5), Scott Strange (D2, 9.5), Simon Thornton (D2, 10.5), Tano Goya (D2, 9.5), Robert Karlsson (D3, 9.5).

• Other orders from the week included new Vokey Design Spin Milled wedges for Mikko Ilonen, Scott Strange and Jose Felipe Lima, plus Scotty Cameron putters for Simon Thornton and Rick Kulacz.
