I recently caught two ships using this modification. It was so successful that I may fit it as standard on all pirate vessels where warp speed is a factor. Although relatively expensive and causes the armour to be affected, the ability to capture prey more often may compensate for the costs involved in both fitting and to the ship’s armour.
For the most part the items needed to construct the rig are acquired from my excursions and therefore the costs are minimal, but it’s important to keep costs in mind. I can imagine this rig particularly useful when hunting for targets in asteroid belts or in larger systems. In one instance a Thorax had literally left the grid as I arrived and, aiming my ship for the targets estimated destination I was able to align, warp and arrive in tandem with the target. This is obviously more pronounced where the distances are greater allowing one to overtake the target in warp.
I will continue to field test this rig on a range of vessels but I can clearly see the usefulness. If the capture rate can be maintained I will roll out this fitting to additional ships as I see necessary.
