Ah, to be honest a better idea would of been just to have one unlocked for everyone and the other stuffed away in a tech broker somewhere (human tech broker needs some serious additions.....). people tend to generally not like the loss of content.... or rather react to it quite severely when they miss out on something much like the Cobra Mk4, forever gone, never again, people still complain about that and will likely will do forever until they add it in some way (like a triple Elite reward or something) The very same will happen if Frontier deny players the choice of either module in this event.
Also, good seeing around Lightspeed! i have been gone for a good few months now on the forums, good to see a popular face once more
