The biggest difference is adjustability. The Qi35 LS has movable weights that testers used to tune spin and shot shape, including shifting weight toward the heel to encourage a draw. The Qi4D LS has only two weights that move front to back, with no heel-toe adjustment, so it tunes spin and flight but not draw or fade bias.
Both are compact 460cc low-spin heads for fast, consistent strikers. Testers agreed the Qi35 LS launches lower for a penetrating flight. Launch reports on the Qi4D LS were split, but it was the lowest-spinning head in its range, and much of its distance came from roll. Both feel solid on centre strikes. Both lose speed on heel misses, and the Qi4D LS also loses speed on toe misses.
Choose the Qi35 LS Driver if…
you want a lower, penetrating flight and movable weights that let you shift the head's bias, for example toward the heel to help a draw.
Choose the Qi4D LS Driver if…
you swing at roughly 100 mph or faster, spin the ball too much, and want the lowest spin with lots of roll and a tight, predictable dispersion, without needing to adjust shot shape.
Common questions
- Which one can be adjusted to help a draw?
- The Qi35 LS. Its movable weight can be shifted toward the heel to encourage a draw. The Qi4D LS has only front-to-back weights and no heel-toe adjustment.
- Which is more forgiving?
- Neither is very forgiving. Each is the least forgiving head in its own family, and both lose noticeable speed on heel misses. Reviews of the Qi4D LS also point to toe misses.
- Which launches lower?
- Testers agreed the Qi35 LS launches lower for a penetrating flight. Reports on the Qi4D LS were split: some saw a lower flight and others a high, strong trajectory.
