Me gusta más el 919 F/D que es muy parecido al 919 THI:

[cell class=spoiler]Features:
Designed for the golfer who needs more control off the tee or wishes a much smaller size driver head.
Thin, variable thickness, high strength steel face for high 0.830 COR for maximum distance.
Bendable hosel for a wide range of fitting options for lie and face angle, +/-4* from spec.
Can also be played off the fairway by more skilled players who want every bit of second shot distance on long holes.
Available in RH in 11* and 14* lofts, cosmetically designed to complement the appearance of the 919THI Drivers.[/cell]
