The Verdict: Spin technology and fitting options define wedge performance. Few are milling this area (literally) like Callaway. There are two types of milled grooves depending on the loft, plus a new process for creating surface friction between those grooves. Instead of cutting into the flat surface between grooves, the MD4 mills ridges that rise from the surface to create more contact points for spin on the shortest shots. As for fitting, the MD4 has more options than ever (21) across nine lofts with four sole grinds.
Loft: 21 options (46-64 degrees, four sole grinds)
