Nearly every week in the GolfWRX Forums, our team is running one or more special influencer threads that allow golfers to win free stuff, try the latest gear, and voice their opinions on what’s good… and what’s not.

Here’s what’s up for grabs this week.

Giveaway: Toulon Garage Rio Olympic Putters

• Winners: 3
• Method of Entry: Forum Post (more below)

Toulon’s new Garage Rio Olympic Putters sell for $699 each, making this a high-dollar giveaway. Make sure you hurry up and enter, as the contest ends Thursday at 6:30 a.m. ET!

Here’s how you do it. First, follow Toulon Design on social media to Twitter, Instagram and Facebook. Then, in this thread, predict the combined four-round score of the gold, silver and bronze medalists. So if you think the gold medalist will shoot 15-under par, the silver medalist will shoot 13-under and the bronze medalist will shoot 12-under, then your predicted, combined four-round score would be 40-under.

The three contest entrants who are closest to predicting the combined four-round score will win. If there is a tie, Toulon Design will hold a random drawing to select the winner.

Apply to Test: OnCore Golf Balls

OnCore Golf was formed by two young entrepreneurs – Bret Blakely and Steve Coulton – who thought making the game of golf more enjoyable through innovative products like a hollow metal core golf ball was a great idea… and it’s catching on with golfers.

Enter to test the company’s two golf balls — the Avant and Caliber — by going to OnCore Golf’s website and signing up to win a free OnCore Players Pack on the bottom of the page. Then, in a post in the forums, answer a few simple questions.

Apply to Test: Matrix Surprise Shaft Contest

• Winners: 10
• Method of Entry: Forum Post (more below)

Matrix has a special shaft for GolfWRXers to try. We won’t reveal what it is, but if you are interested, please apply in this forum thread. If selected, you’ll be contacted and will receive a surprise shaft from Matrix to review.

Member Testing: Graphite Design “Replace Your Driver Shaft”

Last month, we announced Surprise Shaft Testing was coming to GolfWRX. We wanted to know what driver shaft you were playing and if you’d like to try something that might be better for your game. Several hundred people members applied to be part of it, but only five could be picked.

Winners were quizzed on their drivers a bit more, and then were told to expect a package… very soon. They had NO IDEA what shaft manufacturer or model would arrive until they got the box.

When the boxes started arriving, this thread started. The good folks at Pro’s Choice Golf Shafts sent brand new Graphite Design driver shafts, properly tipped with their current driver head adaptor already set. Read what the testers are saying about what they got in the mail, and how it’s performing.

Member Testing: Lamkin Z5 Grips

What’s the story on Lamkin’s new Z5 grips? Five lucky GolfWRX Members won the yet-to-be-released grips. See what they’re saying about them in this forum thread.

Member Testing: ECCO CAGE EVO Golf Shoes

In this thread, you’ll read about the five GolfWRX Members who were chosen to test Ecco’s new Cage Evo golf shoes before their release at retail. See what they had to say.
