A static weight is easier to target than a swingweight, but again the static weight on tw is an average.
The sw on twu is 306 for the standard and 330 for the plus, but on the description pages they are averages.
Both the drive and apd came in with lower average swingweights and the reviews have noticed this, so its accurate.
But because of the perhaps wider variation of spec this time around its more of a lucky dip unless you specifiy what you want with this upgrade.
