Stock shaft: Matrix Ozik Lofts: 3+ (13°), 3 (15°) and 5 (18°)
Tech a4 blends design features
from hybrids and fairway woods.
Its hybrid-like shape and internal
weighting contribute to a 17
percent higher MOI than current
Insight XTD's. The sole curvature
(as in fairway woods) reduces
turf interaction. The thin maraging
steel face and shaft (0.5 inch
shorter than fairway wood)
generate slightly higher ball speed,
21 percent less spin and 5 percent
more length than oversize fairways.
