From the moment Bryson DeChambeau announced he was signing with Cobra-Puma at the RBC Heritage, work was already being done behind the scenes to create a set of single-length irons for the 2015 U.S. Amateur champion. 

The last four months have seen Cobra engineers create multiple sets for DeChambeau, including some initial prototypes made from the company's King Forged MB and CB models that featured tungsten plugs in the heel and toe most heads to get the head weight to his preferred 280 grams. 

With exception of a brief week spent at the Georgia Cup with a set of single-length Cobra irons, DeChambeau has used custom Edel irons for every one of his professional starts — until last week at the RBC Canadian Open. 

DeChambeau, who wasn't in the Open Championship field, spent the off-week prior to his eighth TOUR start working with Cobra on another single-length set — DeChambeau was at the company's headquarters the entire week fine-tuning all aspects of the irons — that went in play for the first time on Thursday. 

When he arrived at the course on Monday, the custom-built clubs had tape across the back of each cavity, concealing the identity and design of the set. He kept the tape on the iron heads for both rounds at Glen Abbey Golf Course. 

DeChambeau remained coy about the irons earlier in the week, offering up that there was "something in the works."

"To be this involved in the process, it's what I've always dreamed of," DeChambeau told PGATOUR.COM of his role in the iron design process. "We were working on it for a week-and-a-half and it's pretty special to see what they are going to have coming shortly."  

Last week, Cobra offered up a peek at the final version of DeChambeau's irons that look similar to the Fly-Z+, with a muscle pad and small cavity visible throughout the entire set. 

Cobra wouldn't comment on the design and specs but did confirm more information would be available later this year. 

In addition to putting new irons in the bag, DeChambeau added a 7-degree Cobra LTD Pro driver (Project X 85X shaft) and 12-degree Cobra LTD 3-wood (Project X HZRDUS 85X shaft), giving him a nearly new bag of Cobra sticks.

Less loft for Day: Warmer than normal temperatures had Glen Abbey Golf Course playing firm and fast during the RBC Canadian Open — especially the greens. One week after playing on Royal Troon's slower putting surfaces, Jason Day had TaylorMade reps reduce the loft on his Spider Limited Red putter by a half degree to adjust for the pacey greens. 

By decreasing the loft on his putter, Day was able to get the ball rolling sooner and reduce the chances of it skidding along the way.

The subtle tweak paid dividends as Day clawed his way back from a second round 76 to finish T14 for the tournament. 

Laird goes high MOI: Martin Laird produced his best result of the season with a runner-up finish in Canada. The strong showing came with a high MOI (moment of inertia) TaylorMade Ghost Spider Si putter that went in play for the first time at Glen Abbey. 

Launched in 2014, the counterbalance model has a 380-gram head and 15-inch, 130-gram counterbalanced grip that improves stability and control. 

According to TaylorMade, Ghost Spider Si has an MOI that's more than 6,000 — standard blade and mallet models have an MOI that ranges from 3,500-4,500 — which makes the putter head more forgiving and resistant to twisting at impact.

Ghost Spider Si comes in two lengths (35 and 38 inches) with a PureRoll Surlyn insert that promotes a smooth roll and solid feel.

Coming into the week, Laird was ranked 85th on TOUR in strokes gained-putting (plus .089). He improved on his season average over 72 holes, finishing 41st in the statistical category (plus .226).
