Nike SQ MachSpeed Black Round

Nike's aerodynamics research led to shape changes: A tapered heel section and a diffuser pattern on the sole aim to reduce drag. The club's total weight is less than 300 grams thanks in part to a 50-gram Mitsubishi Rayon Fubuki shaft. The purpose of the lighter weight is to help players increase clubhead speed. The head also has an eight-way adjustable hosel.

“The neutral setting is actually shut, but if you inch it to the right you can get a good look."..."The ball went straight, even mis-hits."

"Looks substantial. I like the weight. The ball rebounds nicely."..."The square version looks like bathroom tile. Way too loud."

This is a big improvement over last year's model. The larger, faster face and sleeker, less jarring shape are upgrades. A choice of square or round clubhead (with meaningful adjustability) is a plus.

The adjustable hosel borders on dog-collar size, and the square version is a nonstarter for many.
