The extended rear corners of the "boxer" shape are intended to stabilize performance on off-center hits. The shallow-face incorporates the low center of gravity of a hybrid ($180, standard and draw, three lofts, adamsgolf.com).
Callaway Diablo
There are two versions: The N (neutral) features a shallow face based on tour input. The D (draw) is taller and has a draw-bias face angle ($180, seven lofts, callawaygolf.com).
Exotics XCG-V Tour
The multimaterial head features the same titanium cup face, large steel sole plate and light magnesium crown as the original XCG-V, but it has a larger face ($369, four lofts, exoticsgolf.com).
Nike SQ Dymo
Designed to combat the turf interaction problems of larger-headed fairway woods, the angled sole is intended to limit surface contact ($230, five lofts, nikegolf.com).
TaylorMade R9
The adjustable-hosel design features eight settings that change the face angle, lie and loft. Ball-flight options range from neutral to a slightly higher, draw bias to a slightly lower, fade bias ($230, four lofts, taylormadegolf.com).
Titleist 909F2/F3
Two options are designed to accommodate two ball flights. The tour-inspired F3 head shape produces a lower flight. The F2, with a wider and more shallow face, has a lower CG and higher lofts to launch the ball higher ($200, three lofts, titleist.com).
