First Look at Interchangeable-Shaft Drivers By Gary Van Sickle There is good news about the new era of adjustable and interchangeable shafts. You don't have to be Bob the Builder, a member of Jeff Gordon's pit crew or a golf professional to swap shafts in your new adjustable driver. Here's a how-to guide for two adjustable systems that debuted at the PGA Merchandise Show in Orlando, Nickent's Evolver 4DX, left, and Callaway's i-Mix.

Ease factor "If you've ever assembled anything at home with a screw in it, it should be pretty simple," said Jason Maloney of Nickent. This system is remarkably simple and largely foolproof. The screw is pretty small, however, so it will be hard to find if you drop it in the grass. A deft set of hands can make a change in 15 or 20 seconds.

Callaway This is a three-step process. First, slip the shaft and hosel assembly into the opening in the top of the clubhead, making sure they're correctly aligned, and push them together. Second, use your fingers to tighten the nut that holds the two pieces together.Third, use the official I-Mix wrench to turn the nut several rotations until it makes a loud clicking sound. That noise indicates that the assembly is locked in place.

Ease factor At a Callaway outing, beginners fumbled with the procedure at first but began to get the hang of it on the second and third attempts. Initially, it took between 90 seconds and 2 minutes, but the Callaway experts were slapping clubs together in 20 seconds.
