FAIRWAY WOOD: Titleist 915F (15 degrees), with Mitsubishi Diamana ZF 70X shaft

Some pros hold on to a fairway wood for a few years, but by Tour standards this is a relic. The first Titleist 915F fairway woods began to show up on the PGA Tour in June 2014 and were released at retail that September. 

Back then, the feature that raised some eyebrows was the Active Recoil Channel (ARC). The ARC was a slot cut into the sole of the club behind the leading edge that was designed to allow the lower portion of the hitting area to flex more effectively at impact. That helped increase ball speed on thin shots and reduce spin for a lower flight and more ball speed.

The ARC was covered by a polymer to keep water and debris out and improve turf interaction, and it’s a feature that is still designed into Titleist fairway woods today.

The 915F was not the first club to feature a slot cut into the sole, but it was Titleist’s first fairway wood to include the design, so golfers took notice.

The 915F was replaced by the 917 fairway woods in September 2016, but Golfweek found several used clubs on eBay, like this one, for between $75 and $125.
